Virtual full not working after upgrade to 9.5u4

Post by holzhei » Mar 13, 2019 11:36 pm 1 person likes this post

On Saturdays we schedule a full tape backup and then have incrementals to tape Sunday, Monday, Tuesday, Wednesday, Thursday, Friday. The source jobs are 10x backup jobs, and 2x backup copies. The 10x backup jobs have active fulls run every Saturday, which in turn forces a full backup to tape every Saturday (and the virtual full setting is ignored), and then incremental are backed up to tape every other day. The 2x backup copies are forever forward, and from my understanding should have a virtual full backup (vbm) created on the tape full backup day (Saturday), and incrementals are backed up to tape Sunday, Monday, Tuesday, Wednesday, Thursday, Friday. This was working for us on 9.5u3.

Since upgrading to 9.5u4 a few weeks ago, the virtual fulls are not created reliably to tape for the 2x backup copy jobs. Some times the are created on the Sunday run, other times they are not created at all.

For instance this week one of the backups copy jobs had the virtual full created on Sunday, and the other one has still not created a virtual full, only incrementals on Saturday, Sunday, Monday, Tuesday, Wednesday.

Any hints on where I should be looking?

Case number is 03432873

Hello,
and welcome to the forums.

As you say that you did not change anything and it worked with U3, the only thing I can recommend is to continue working with support. Also your observation with "sometimes they are created, sometimes not" seems strange to me.

There seems to be a typo in the case number, as the stated case was closed with "no answer from customer" some time ago.

Best regards,
Hannes

That sounds like a problem I have, since U4 getting synthetic fulls to tape for one of my backup copy jobs is hit and miss. I have 2 BCJs and several local full backups. the local backups generate a synthetic full to tape each night but the BCJs are the problem.

my case# is 03442611

I will update my case and reference your case ID

We logged two cases, but got similar responses each time saying that this is normal as the incremental is locked. Previously it would create a virtual full with the latest available incremental (which may have been the previous one if the latest was locked, and we were okay with that). Looks like u4a was just released with reliability fixes for tape, although it does not go into much detail.

After not being able to get the normal tape backups with incremental working, we switched to a GFS media pool which now allows daily incremental since the u4 upgrade. Although we aren't able to schedule it to run after our last backup job like we could with a normal tape job.

@holzhei: it would help me to search for details if you could post the case numbers here. Nathano is currently testing U4a but I cannot see a case update yet (is "on hold")

I'm still working with support on the issue.. next thing I am trying is this.. will see if it backs up OK tonight.

"
Hi Please remove the backup copy job from the configuration and re-import the backup.

1. Open the Home view.
2. Disable the backup copy job.
3. In the inventory pane, select backups-> disk(copy).
4. In the working area, right-click the backup copy job ->right click->select "remove from configuration".
5. select Backup infrastructure view-> rescan backup copy repository
6. The backup files will appear under backups-> disk imported.
7.Edit the backup copy job->target->map backup->select the backup copy job.
8. This will move the backup files from disk imported -> disk(copy).
9. Edit the tape job->remove the backup copy job and re-add.
10. Run the backup tape job.

the above steps looked like it fixed the problem, but no, last night both BCJs were left off the tape.

This is getting ridiculous.

Hello Nathan,

I've asked QA folks to review your case. I'll let you know once I hear back anything. Cheers!

I hope there's a resolution soon, our backup to tape is a critical part of our backup strategy, you know, 3-2-1 etc..

There should not be a green tick next to a component of the job that failed to backup any data, as you can see in this screen shot, it failed to capture any data for one of the requested backup to tape components and it still ticks it off as green! Crazy stuff, this has to be a warning, can this please be logged as a feature request.

I'm having a similar issue - although I am new to Veeam so not sure if it would have worked in the past. I cannot get a backup copy to create a synthetic full for a specific day, all it does is just copy the oldest full to the tape. If I alter the same job using the same media pool and choose a VM with a backup source (rather than a backup copy) it creates the synthetic full as expected.

I've moved from Backup exec to Veeam and beginning to pull my hair out over this product! I have logged a ticket 035142 but would like some help from anyone here if they can. I am running 9.5u4a

Sorry for keeping silence. Was told that this behavior looks like a known issue and we already working on a private fix. Please keep in touch with your support engineer. Please let me know how it goes!
