BCJ with GFS enabled creates 2 Weekly VBK files

Veeam Logoby Hoegimator » Fri Apr 21, 2017 8:52 am

Hello all,

We are running B&R v9.5 and our Backup Copy Jobs create two weekly fullbackup files, if the option "Read the entire restore point from source backup instead of synthesizing it from increments" is enabled.
As an example, lets take a single fileserver-BCJ with the above option enabled, GFS enabled (Weekly backup on Sunday 06:00). This bcj creates a VBK file for the Saturday AND Sunday job.

I don't understand why that happens...

Any thoughts on that?

Thanks

The GFS retention is:

Weekly 4
Monthly 2
Quarterly 2
Yearly 0

In fact we have 4 Weekly fullbackups: 08.April / 09.April / 15.Arpil / 16.April
I cannot see a reason to have a .vbk on Saturday 08.&15.April and Sunday 09.&16.April. This makes no sense....

Hello Joerg,
Looks like Saturday .vbk is full backup of the main chain while Sunday`s one is a part of GFS retention.

This seems strange though. Could you check which of the full backups relate to GFS retention? The backups should have such postfixes as W M Y.

That`s turned to be a bug which was investigated recently. It`s going to be fixed in the next major release.
The workaround is to disable the mentioned check box.

Here is a fresh workaround to get only one full backup with "Read the entire restore point from source backup instead of synthesizing it from increments" enabled.
What you need to do is just to set time of weekly GFS point creation later than job starting time.
Thanks!

In my example above (FileSrv005-CopyJob), the job starting time is 09:30pm and the "weekly GFS point creation" is at Sunday 06:00am. I'm not sure if that workaround works....

Yes, that`s a buggy configuration. Have you tried to schedule "weekly GFS point creation" afternoon and the job starting time at morning?

Yes I tried that, didn't make a difference.

On another job, where I disabled "Read the entire restore point from source backup instead of synthesizing it from increments" the incremental files are not deleted anymore.

The GFS settings are:
Restore points to keep: 14
Weekly: 4
Monthly: 4
Quarterly: 1
Yearly: 0

On version 9.0 it work fine.

That`s an unexpected behavior.

Yes dis is unexpected and I found other jobs, also backup jobs, with similar problems.
The fix for me was to temporary change the number of "Restore points to keep", a.e. on the bcj above I changed it from 14 to 11 or on a backup job from 30 to 29, and run the job again.
