VBR – Mac Backup

Veeam Backup & Replication (VBR) version 11 has a new feature and Mac users will fall in love with it.

It is now available for the backup and restores of your MACOS files.

It supports the last Operating Systems starting from High-Sierra (Big Sur 11.X.X / Catalina 10.15.X / Mojave 10.14.X / High Sierra 10.13.6).

Note 1: The Veeam Agent for Mac (VAM) version 1 supports the M1 processor via Rosetta.

Note 2: The VAM supports consistent data backup with snapshots for the APFS file system.

In the other file systems, the backup is created via a snapshot-less approach.

Note 3: At the moment it’s possible to perform the backup of user data (with a custom scope too). The image of the entire machine and a Bare Metal Restore are not available yet.

The configuration steps are quite easy as shown in the official guide:

To recap, the procedure consists of:

  1. From the VBR console create a resource group using a flexible scope
  2. Copy the files generated from VBR to the MAC to protect
  3. Install the package to your machine and import the created configuration. (It allows the communication between VBR and the Mac)
  4. From the VBR console creating the backup policy and apply it

The following video shows how it works in a managed VBR architecture.

Take care and see you soon.

VDrO v.4 – Run a DR plan

This is the last article about how to integrate the Continuous Data Protection (CDP)  technology (available from VBR v.11) and VDrO v.4 (former VAO).

In this part, we are going to see what happens when an orchestration plan is launched.

Yes, I wrote the word “see” because I created a short video showing the tasks that are automatically completed when a Disaster Recovery is occurring.

If you need more details about how to set up the environment, please read the previous articles.

Let me know if videos and youtube platform are a good way to expose technological valuable topics.

Thx for reading and watching and take care

Digital Trasformation & Data Mobility

Se negli ultimi 5 anni, la parola Cloud è stata quella più utilizzata (anche in modo inappropriato), negli ultimi cinque mesi la parola che sta rieccheggiando di più nel mondo IT  è Digital Transformation.

Da Wikipedia:

“Digital Transformation (DT o DX) è l’adozione della tecnologia digitale per trasformare servizi e aziende, sostituendo processi non digitali o manuali con processi digitali o sostituendo la tecnologia digitale precedente con la tecnologia digitale più recente”.

Ancora: la Digital Transformation deve aiutare le aziende ad essere più competitive attraverso la rapida implementazione di nuovi servizi sempre in linea con le esigenze aziendali.

Nota 1: La trasformazione digitale è il paniere, le tecnologie da utilizzare sono le mele, i servizi sono i mezzi di trasporto, i negozi sono i clienti/clienti.

1. Tutte le architetture IT esistenti possono funzionare per la Trasformazione Digitale?

Preferisco rispondere ricostruendo la domanda con parole più appropriate:

2. La trasformazione digitale richiede che dati, applicazioni e servizi si spostino da e verso architetture diverse?

Sì, questo è un must ed è stato nominato Data Mobility.

3. La Data-Mobility significa che i servizi possono essere indipendenti dall’infrastruttura sottostante?

La miglior risposta credo che sia: nonostante al giorno d’oggi non esista un linguaggio standard che permetta a diverse architetture/infrastruttura di dialogare tra loro (on-premises & on cloud), le tecnologie di Data-mobility sono in grado di superare tale limitazione.

4. La Data Mobility è indipendente dai fornitori?

Quando uno standard viene rilasciato, tutti i fornitori vogliono implementarlo al più presto perché sono sicuri che queste funzionalità miglioreranno le loro entrate. Attualmente, questo standard non esiste ancora.

Nota 3: penso che il motivo sia che ci sono così tanti oggetti da contare, analizzare e sviluppare che lo sforzo economico per farlo non è al momento giustificato

5. Esiste già una tecnologia Ready “Data-Mobility”?

La risposta potrebbe essere piuttosto lunga ma, per farla breve, ho scritto il seguente articolo che si compone di due parti principali:

Livello applicazione (contenitore – Kubernetes)
Livello dati (backup, replica)

Application Layer – Container – Kubernetes

Nel mondo IT, i servizi sono eseguiti in ambienti virtuali (VMware, Hyper-V, KVM, ecc.).

Vi sono ancora alcuni servizi che girano su architetture legacy (Mainframe, AS400 ….), (vecchi non significa che non siano aggiornati ma solo che hanno una storia molto lunga)

Nei prossimi anni i servizi verranno implementati in un’apposita “area” denominata “container”.

Il contenitore viene eseguito nel sistema operativo e può essere ospitato in un’architettura Virtuale/Fisica/Cloud.

Perché i contenitori e le competenze su di essi sono così richiesti?

a. L’esigenza degli IT Manager è quella di spostare i dati tra le architetture al fine di migliorare la resilienza e ridurre i costi.
b. La tecnologia Container semplifica la scrittura del codice dello sviluppatore perché ha un linguaggio standard e ampiamente utilizzato.
c. I servizi eseguiti sul container sono veloci da sviluppare, aggiornare e modificare.
d. Il contenitore è “de facto” un nuovo standard che ha un grande vantaggio. Superare l’ostacolo della mancanza di standard di comunicazione tra le architetture (private, ibride e cloud pubblico).

Un approfondimento sul punto d.

Ogni azienda ha il proprio core business e tutte hanno bisogno della tecnologia informatica.

Qualsiasi dimensione dell’azienda?
Sì, basti pensare all’ uso del cellulare, per prenotare un tavolo al ristorante o acquistare un biglietto per un film. Sono anche abbastanza sicuro che ci aiuterà a superare la minaccia Covid.

Questo è il motivo per cui continuo a pensare che l’IT non sia un “costo” ma un modo per ottenere più successo e denaro migliorando l’efficienza di qualsiasi azienda.

Anche Kubernetes ha delle  funzionalità specifiche per consentire la mobilità dei dati?

Si, un esempio è Kasten K10 perchè ha tante e avanzate funzionalità di migrazione dei workload (l’argomento sarà ben trattato nei prossimi articoli).

Data-LayerCloud Backup Restore Icona - Download gratuito, PNG e vettoriale

E i servizi che non possono essere ancora  containerizzati?

C’è un modo semplice per spostare i dati tra diverse architetture?

Sì, è possibile utilizzando copie dei dati di VM e Server Fisici.

In questo scenario aziendale, è importante che il software possa creare backup/repliche ovunque si trovino i carichi di lavoro.

È abbastanza? No, il software deve essere in grado di ripristinare i dati all’interno delle architetture.

Ad esempio, un cliente può dover ripristinare alcuni carichi di lavoro on-premise della sua architettura VMware in un cloud pubblico o ripristinare un backup di una VM situata in un cloud pubblico in un ambiente Hyper-V on-premise.

In altre parole, lavorare con Backup/Replica e ripristino in un ambiente multi-cloud.

Le immagini successive mostrano il processo dei dati.

L’ho chiamato “Il ciclo dei dati” perché facendo leva su una copia di backup è possibile spostare liberamente i dati da e verso qualsiasi Infrastruttura (Cloud pubblico, ibrido, privato).

Le immagini 1 e 2 sono solo esempi del concetto di mobilità. Possono essere modificati aggiungendo tutte le piattaforme supportate dal software di cloud mobility.

Il punto di partenza dell’immagine 1 è un backup in locale che può essere ripristinato in locale e nel cloud. L’immagine 2 mostra il backup di un carico di lavoro sito in un cloud pubblico ripristinato su cloud o in locale.

È una via circolare in cui i dati possono essere spostati tra le piattaforme.

Nota 4: Un buon suggerimento è quello di utilizzare l’architettura di mobilità dei dati per configurare un sito di ripristino di emergenza a freddo (freddo perché i dati utilizzati per ripristinare il sito sono backup).

Immagine 1

Immagine 2

C’è un ultimo punto per completare questo articolo ed è la funzione Replica.

Nota 5: Per Replica intendo la possibilità di creare un mirror del carico di lavoro di produzione. Rispetto al backup, in questo scenario il carico di lavoro può essere avviato senza alcuna operazione di ripristino perché è già scritto nella “lingua” dell’host-hypervisor.

Lo scopo principale della tecnologia di replica è creare un sito di ripristino di emergenza a caldo (DR).

Maggiori dettagli su come orchestrare il DR sono disponibili su questo sito alla voce Veeam Disaster Recovery Orchestrator (conosciuto anche con il nome di Veeam Availability Orchestrator)

La replica può essere sviluppata con tre diverse tecnologie:

  • Replica Lun/Archiviazione
  • Split I/O
  • Snapshot

Tratterò questi scenari e i casi aziendali di Kasten K10 in articoli futuri.

A presto

A flexible file backup Strategy – Part 4

This is the last article about NAS series.

The scope is recapping the different technology available for NAS backup pointing in which scenario they can be adopted.

The following table has the scope of helping and discovering which VBR technology can better fit with the NAS protection service.

Technology v.11 and later NAS Backup File to Tape NDMP
 Backup to Disk Yes No No
 Backup to Tape No Yes Yes
 Restore Files Yes Yes No
 Restore Entire NAS Yes Yes Yes
 Speed Backup High Low Medium
 Speed Restore High Low Medium
 Second copy Yes to Disk v.11  (Tape cloning) v.11 (Tape cloning)
 Archiving copy Yes No No
 Immutability v.11 (Hardened Repository) Yes Yes
 Object Storage Yes No No
 Scheduling Yes Yes Yes
 Licensing VUL Any Enterprise Plus

Table 1

An example:

Your managers are asking for a NAS backup architecture able to answer very astringent requests of backup and restore.

Watching table 1 and looking for the word speed it is possible to assess which VBR technology can answer the request of your managers better (in this case v.10 and later NAS backup).

Note-1: For sure the table can be improved by adding more details.

Note-2: The second tape copy and harden repository will be available with VBR v.11. Further details are available on the following web pages:

(https://community.veeam.com/blogs-and-podcasts-57/tape-improvements-in-vbr-v11-277)

(https://community.veeam.com/blogs-and-podcasts-57/veeam-v11-hardened-repository-aka-immutable-backups-275)

Note-3: v.11 is coming soon !!! Please take a look at the launching page and register yourself: https://go.veeam.com/v11-it.

Before closing this series, I show you a hidden gem that allows extending the use of the file copy feature.

What is “File Copy” option already present on the VBR menu?

It allows to copy and move files and folders between servers and hosts added to the backup infrastructure.

Is it possible to use it with Network share?

Not in a direct way.

Actually, No becomes a yes through the PS-tools.

What these tools are?

It is a free utility part of the Sysinternals pstools suite built by Mark Russinovich many years ago.

They allow the administrators to remotely execute commands, install software, launch applications, and run apps as the system account.

The PS-Tools package can be downloaded from the Microsoft web site:

(https://docs.microsoft.com/en-us/sysinternals/downloads/pstools)

A detailed guide is available on the following site:

Psexec: The Ultimate Guide

Which are the requirements?

Important Note:  File copy is a copy. It means that if you launch the same job twice, the second time it will delete the files previously saved. It’s like launching two times a copy command without changing any option. To be clearer, it’s not a backup so it can not manage retention policy,  nor deduplication/compression.

Note-4: I don’t know if this scenario is supported by Veeam, open a ticket before proceeding.

The following video will explain the steps to set up the environment, perform backup and restore (ps-tools are located to c:\Users\VBR\Desktop\PStools)

That’s all guys. Take care

A flexible file backup Strategy – Part 3

This article’s topic is how to set up and work VBR when it is combined with the NDMP protocol.

This type of configuration is part of the category “file to tape” I treated in my last article “A flexible file backup Strategy – Part 2”.

One more note before starting: VBR requires NDMP version 4 and later.

  • How does it work?

Picture 1

The architecture is quite easy.

Files are gathered from the File Server through the data mover present on the Gateway server. Then they are sent to the Tape Server that performs the write on Tape.

The Datamover installed on Tape Server has the ownership of managing the data traffic to Tape Device.

VBR has the task of enumerating the Volumes and launch the command to Tape Devices.

Point-1: VBR works with a 3 layer backup architecture. It means there is no direct connection between File Servers and Tape Devices. All Data have to pass through the tape Sever.

In this article, I’m not covering the procedure to set up the NAS correctly. Please ask your storage vendor specialist to get all details needed.

How to add the NDMP server to VBR and set up a backup job?

The next video will answer the question.

Video 1

After the backup is completed how to perform a restore?

NDMP backup files are available to perform restores from the FILE menu at the voice Tape and then NDMP as shown in picture 2

Picture 2

 

Please have a look at the next short video (video 2) to see the easy step to perform a restore.

Video 2

Point-2: The backup chain stored on tapes will consist of 10 restore points maximum. On the 11th run, VBR will force an active full.

  • Common scenarios

One of the main characteristics of NDMP backup is that it allows to perform backup and restore of entire volumes.

The most common scenario is the Disaster Recovery of the entire Filer. Imagine the case in which the customer NAS filer is completely out of order and the only way to restart the file sharing service is formatting all the disks and then restoring the volumes (or the worst case is getting a new NAS).

In this case, NDMP volume restores from tape is an excellent low-cost solution.

Main Pro:

NDMP servers backup to tape is available in the Enterprise Plus Edition of VBR.

It means that there is no limit on the amount of data that can be saved. Could be 1 TB or 100 PB it doesn’t matter.

Veeam Universal License (VUL) has the Enterprise Plus Edition available. Is it time to move your old sockets license to the subscription model (VUL)?

Cons:

The granular restore (files and folders) it’s not an available option with VBR and NDMP backup.

Please note that NAS backup is now completely supported by VBR (please refer to article 1 of this series) and it’s the fastest way to perform the granular restores.

Point-3: Even if the NAS device supporting NDMP protocol is already added to VBR, you need to add the NDMP server as a separate procedure. Otherwise, you will not be able to perform file backup to tape.

The next article will cover a recap of the different techniques and show a hidden gem of VBR.

See you next week and take care

A flexible file backup Strategy – Part 2

In this second article, we are going to cover the File to Tape strategy.

Why tape devices are still widely present in the IT department?

  • It’s a good way (but not the only one) to manage the offline backup data (read it as improving the Security Strategy of your data).
  •  Media can be easily carried or moved (read it as Portability).
  • Deployment is often very quickly (read it as speeding up the adoption).
  • It has a potentially infinite capacity (Just adding media).
  • The LTO is a neverending technology in a continued evolution.
  • The tape is a well-known device, IT operators have the skills to manage it.
  • The costs for GB is lower than disk technologies.
  • The costs are quite predictable, managers can budget it easily.

VBR needs a Windows Physical Server named Tape Server to control the Drives and Robotic, LTO3 or later Drives, and MS-Windows drivers (supply by the hardware vendor).

The official user guide available on the Veeam site gives all detailed info.

Just a note before starting:

VBR uses Tape Technology in two different ways.

The most used one is back up to tape (Picture 1).

In this case,  the source backup data are the backups already present and created with a backup job or backup copy job.

They are saved to Repository (Repository is a Disk technology).

It means that the scope of backup to tape is to pour out data to tape.

Picture 1

Please have a look at the following video (https://www.youtube.com/watch?v=Il8mH2KB_Uo) to get more details.

The second way is File to Tape and it is the topic of this article (picture 2).

https://lnx.gable.it/wp-content/uploads/2021/01/nas-7.jpgPicture 2

Which type of source files can be saved to tape?

  • Windows & Linux servers (virtual or physical doesn’t matter)
  • NAS file share (SMB (CIFS) and NFS ).
  • NDMP filers (it will be covered in the next article).
  • How does it work?

Picture 3

Picture 3 shows the data streams when a tape process is performed:

  1. The main components are Data Movers. These Services run on the source and on the Tape Server.
  2. VBR triggers the source Data Mover to perform a copy of the files to the target. At the destination, the target Data Mover check if the files have arrived correctly.
  3. The tape Server manages the write operation to the tape also.
  4. VBR stores all info about files saved (media used, retention, etc.)  in a catalog.
  5. In the restore scenario, the step order is four to one.
  • *Note: To perform a backup of Windows and Linux servers, it is requested to add those servers to the managed server as shown in picture 3. Through this process, the Data mover service is properly installed.
  • Network Share: Adding SMB/NFS Share as shown in the previous article (A Flexible file backup strategy – Part 1).
Picture 3
  • Common scenarios

File to Tape backup can be used by any customer. You need just a Tape Server, Tape Devices, Drivers, and VBR.

There are at least two main cases:

  • Customers who want a copy of their data to tape.
  • Customers with a small budget who doesn’t need rapid restore

The next video will show how to set it up.

Main Pro

  • There is not a room limit. It means the license doesn’t count how many GB, TB, PB will be written to Tape.
  • The VBR architecture is as usual flexible. It’s possible to add more tape servers and more than 1 tape library.

Version 11 will add more great features:

  • Tape cloning (https://community.veeam.com/blogs-and-podcasts-57/tape-improvements-in-vbr-v11-277)
  • Tape verification (https://community.veeam.com/blogs-and-podcasts-57/part-ii-tape-improvements-in-vbr-v11-289)

Cons

*This behavior is quite common to all backup software that writes data directly to Tape.

  • For saving a file, VBR needs to trigger a process of discovering the file to the source, gathering and writing it to a media.

If you consider that the common NAS scenario is composed of millions of small files and thousands of folders and that the tape technology has to choose for every file the location in the media (where the file will be copied)  it’s clear that this process, common to all backup servers, stresses the hardware architecture and in particular the drive header.

The backup process has a small speed advantage compared to restoring because writings to media are often sequential and not random.

Image to restore 10k files located in 10k different positions in a single tape.

The drive has to perform a great job. It is going to suffer from an effect called shoe-shining (also known as tape back-hitching)  which occurs when a tape drive cannot transfer data at an acceptable speed.

Shoe shining can contribute to data loss over time, as the repeated back-and-forth motion will wear the tape drive’s read/write heads and negatively affect the readable portion of the tape

  • Loss of Tape Cartridge Capacity
  • Increased Risk of Read/Write Issues
  • Excessively Worn Tape Drive Heads
  • Low Data Transfer Rates
  • Data Loss
  • The Veeam DB needs to be sized correctly and the best practice is to switch from SQL Express to SQL Standard
  • Media management is quite challenging when the amount of tapes is big. Remember to store them in a fireproof and non-magnetic safe.

Do you also prefer the NAS backup feature introduced in v.10? Let me know!

That’s all for now.  

See you next week for talking about NDMP
