Hi there,
I was wondering if anyone noticed something like this in their
environment, I have a bacula director ver 11.0.6. (10.3.2022)
connecting to serveral clients with versions from 5 onwards. I have
this particular client which runs on debain 12. ver. 9.6.7(20dec20),
underlaying storage is ZFS.
The underlying storage is ~800gb in size. All of the sudden incremental
backups started to increase exponentially
1.4. - 93M
2.4. - 574.5M
3.4. - 115.5GB
4.4. - 951.3GB
5.4. - 1.7TB
6.4. - 2.5TB
7.4. - 3.4TB
8.4. - 4.1TB
9.4. - 4.7TB
10.4.- 5.4TB
so last backup says 5,471,496,436,363 (5.471 TB) written, and last 4
backups from this client with several others were written to this tape
which is LTO6 - so max 2.5TB should be written (6.25 compressed).
For some reason estimation of the size of the backup is way off and
data written on the tape as now that tape says it has 18T written -
Vol. bytes 18.3TB
which is absolutely wrong...
even if I move that data to some other folder on that server I get the
same result.
Any ideas?
Borut
Have you got Accurate set to Yes in JobDefs?
My ZFS systems are Solaris, so YMMV.
Cheers,
