How to verify tape backup content and integrity

Case ID:01786446

We have Veeam 9.0 update 1 running on a VMware Esxi 5.1 environment with a Dell TL2000 Tape drive connected with SAS to a Windows Server 2012 physical server. We recently replaced an LTO4 tape drive with an LTO6 tape drive. We tried to do a monthly backup were not able to and are working with Veeam tech to determine cause of the backups stalling and then resuming but no errors reported. In the mean time, we reran the monthly backup on the LTO4 drive and it used several tapes less than usual. Is there a tool or process to verify the contents and the integrity of that backup to determine if it is reliable for us to use?

You can manually start a recovery process to check that backup files are operational.

If we start a manual recovery process and it is not a complete backup how do we stop the process so we do not overwrite the good data that we have?

You can restore the backup to the staging repository and then start a file level recovery (there is no need to perform a full VM recovery). If you are using a file to tape backup – just use non-original destination for restore purposes.

There must be a better way to verify backup tapes!

Your proposed procedure requires sufficient space on the staging repository - this is simply not available for the huge fileservers in our backup Scenario.

dweide,

Unfortunately, that is the only way to verify that you backup is fully operational in current version.

Hello Dima,

yes, if the subject is to verify "fully operational" backups.

But my point is to verify and check the function of the LTO tape drives.
Any plans for the upcoming releases?

dweide,

LTO drive performs an automated verification technology itself during write operations. When data is written to the tape it is verified by the read heads that are positioned behind the write heads.

Can’t say about all, but latest LTO drives have it.

[MERGED] Veeam 7 tape and verify

Veeam Logoby zoltank » Tue Jan 10, 2017 5:40 pm

What's the status on this feature?

I'm in the middle of migrating my tape backup to Veeam, but not having tape verification is a complete show stopper for us. I've had tapes fail verification before, and the thought of an unverified tape failing in a DR situation makes me nauseous.

There is no such feature at the moment.

However, providing you're using combination of SureBackup and latest LTO drives, this should be enough to get required confidence. SureBackup confirms recoverability of backup data, and built-in drive mechanism verifies that data archived to tapes does not change anyhow.

Thanks.

No, it's not. LTO verification only verifies that what the tape drive received is what's written to the tape, and SureBackup only verifies the backup on the hard drive is good. Tape verification makes sure it was also read from the hard drive correctly and transmitted to the tape drive correctly. It's actually shocking to me that Veeam doesn't have verification and is saying it's not needed.

However, it's my understanding tape verification is expected in the next major release.

[MERGED] Restore Tape Backup to Virtual Lab?

Veeam Logoby clovella » Thu Jun 22, 2017 5:02 pm

Hello All,

Apologies for any rule-breaking or confusion, as this is my first time posting here.

I work for a smaller business with around 200 users and we're looking to streamline our processes and save some space. I've been tasked with documenting the Restore from Backup procedures, but before I begin, I was assigned the sub-task of configuring a way to utilize our Virtual Labs as Backup Repositories for Restore from Tape and Restore from File backup recoveries.

I have been reading, and reading and reading and reading.. so much so that these letters are beginning to run together.

Is this even possible?

Help!

Thanks!

Hi, Cassey,

Welcome to our community forums.

Answering your question, there is no such thing as SureBackup for tape backups. You can either confirm VMs recoverability by restoring VMs from tapes or validate backups before they get archived (recommended approach).

Thanks.
