Dear bacula list,
I'm having a weird problem with incremental backups of one of our machines.
We do an online (to disk backup) compressed incremental backup into
single volumes (one volume per incremental job, 10 volumes recycled
automatically) and everything appears to work fine.
However, the on-disk usage of the volume is a whopping 170GB, but when
I do a complete restore of this incremental job the restored directory
occupies only around 60GB of diskspace.
Here's a bacula web statistic from one of the incremental jobs:
460031 Incr 1920 170.45 GB 2018-06-14 16:52:11 2018-06-14 18:52:32
02:00:21 24.17 MB/s 0.05
And here's the "du -sh" report on the fully restored incemental ("mark
*" in "/") job listed above:
bacula_restore]# du -sh .
96G .
We don't get any error messages during restore except for two tomcat
logfiles which changed in size during the backup, but those are only a
few hundred MB and don't account for the huge difference in disk space
usage we're experiencing here.
Also, the restore logs shows some messages in the form of
"file XXXX has been deleted",
but those are also mostly files that are nowhere near large enough to
explain the discrepancy in size. We've also tried removing the
"accurate" flag from the job in question and reloading the config, but
that hasn't solved the problem, either.
We've been running bacula for over a decade now on six backup server
instances with hundreds of clients and a few dozen TB of archive
space, so I'd not consider myself a bacula newbie in the sense of the
word, but this one has me puzzled... any advice would be greatly
appreciated.
Server version: 9.0.6 compiled from source on centos6
Catalog DB: MariaDB 10.x
Client fd version: bacula-client-5.0.0-13.el6.x86_64
bacula-common-5.0.0-13.el6.x86_64
Thanks very much in advance for any ideas on the matter & all the best,
Uwe
