How to disable VBK rename after maintenance task?

Veeam Logoby Luke_TCX » Mon Apr 18, 2016 4:33 pm

Hi,
we need VBK files, created by reversed incremental jobs, without timestamp in the file name.
Registry key DisableVBKRename=1 did the trick for us, until i add maintenance
(defragment and compact task) to the jobs.

Every time, after maintenance, VBK files got standard file name, with a timestamp,
and if i want back to short name, a have to remove current files and create new ones.
It doesn’t matter, if backup job is imported from Veeam 8, or created new in v9.

We have Veeam Backup v9, and last update didn’t help (9.0.0.1491).

Is it known problem, or i should do something else to get short VBK file names?

Not a known problem, as far as I can tell. I've discussed this with R&D and we'll look at the issue closer. Thanks for the heads up.

Thanks for replay. I hope you could reproduce this issue in your environment.

We have plans to expand our Veeam Backup system on new servers
and static VBK names will be very important for us.

Hmm, we stopped supporting this key as soon as we added Backup Copy jobs to the product. The key was only needed before Backup Copy jobs existed, because the only way to copy backups efficiently was using rsync or alike. What is your use case for using this key?

I used static names on VBK files for “Files to Tape” jobs.

But now i see, i overlooked something.

Before maintenance option was added, i did full backups periodically on reversed
incremental jobs, and i had two VBK files in one folder sometimes.

But now, with maintenance, instead of single file, i can add to job whole
folder with *.vbk mask, and this should work.
I'll have one VBK file in one folder most of the time, and that’s fine for me.

I think, this is end of case, thanks for your time and help ;)

Correct. You can select the whole folder and by specifying corresponding file mask make a files to tape job copy only full backup files. Thanks.

Hi,

Is registry key DisableVBKRename=1 supported again in Veeam Backup v9.5 ?
I would have liked my .vbk files not to be renamed, in my forever forward incremental job, even with maintenance tasks (corruption guard & defrag) activated.

Thank you very much !

Sounds like it still works in 9.x : https://www.veeam.com/kb1076
But is it now compatible with maintenance tasks ?
Thank you again !

They registry value works, but not in case of compact operation. Could you please clarify your use case for using this key?

Thank you very much Foggy for your answer.

My use case is the following.
I use rsync to sync the forever incremental repository to an offline location.

Let's imagine we are Monday night, the generated .vib is quite huge.
It is merged to the .vbk.
Then sync to offline location starts.
As the modification made to the .vbk file is very big, unfortunately, the sync did not complete in its allowed time frame.
The partial uploaded .vbk file is however kept offsite.

We are now Tuesday night.
Let's imagine the generated .vib is quite small.
It is merged to the .vbk.
Then sync to offline location starts.
Unfortunately, as the .vbk filename has changed, the offsite partial .vbk file is not considered, and sync restarts uploading all blocks from the huge Monday backup.

If .vbk filename had remained the same, sync would have restarted from where it stopped on Monday night, thanks to the offsite partial .vbk file.
And it would certainly have properly finished.

If the registry value still works for jobs without compact operation, I think it should be quite easy to support it when compact operation is enabled ?
Would be really really nice to see this in the next update.

Foggy, thank you very much for your support !

Any reason why you're using rsync instead of backup copy? With backup copy you wouldn't see this issue.

Because our offsite infrastructure does not include Windows / Veeam servers, so we can't use the "Backup Copy" feature to our offsite location.
This is why we use rsync, targeting UNIX servers.

You can use Linux server as backup repository as well.

Thank you Foggy for the link.
I would have however liked to continue using rsync.
Could it then be possible to think about supporting DisableVBKRename=1 even if maintenance tasks are enabled ?
Thank you very much again !

Foggy, one question, if I set DisableVBKRename=1 with a weekly maintenance task enabled, will rename of the .vbk file occur everyday, or only once a week after maintenance task ?
If I set this registry key for an already started job, do I need to launch a whole new full backup for the key to take effect ?

Thank you very much for your support !
