Hello,
execution time for backups thru Linux clients is very long.
I have noticed this problem for a long time but finally made up my mind
to open a topic about it in the forum.
These are the simple facts:
- 12.07.16 23:03:09: Copying www on dev7
12.07.16 23:03:09: No files need to be copied
13.07.16 01:25:56: Snapshot stored, 772 MB
13.07.16 01:26:11: Comparing www on dev7
13.07.16 01:26:59: Execution completed successfully
Duration: 02:23:49 (02:16:46 idle/loading/preparing)
As you can see even if no files needed to be copied, the backup with
this Linux box takes nearly 2 and a half hours where copying and comparing
appearently only take a few minutes.
It gets worse when there are actually files to copy.
Is there a way to speed the execution up to mopderate speed so
that backing up Linux boxes doesn't hog my nightly backup schedule?
Linux client is 9.5.0.113
OS of the Linux box is
3.13.0-30-generic #55-Ubuntu SMP Fri Jul 4 21:40:53 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Although this paricular client box (dev7) seems somehow extreme other Linux
clients in my nightly backup plan are slow as well:
- 12.07.16 22:06:17: Copying www on dev5
12.07.16 22:44:12: Snapshot stored, 373 MB
12.07.16 22:44:26: Comparing www on dev5
12.07.16 22:45:17: Execution completed successfully
Completed: 22 files, 281,5 MB
Performance: 234,6 MB/minute (146,8 copy, 582,4 compare)
Duration: 00:39:00 (00:36:36 idle/loading/preparing)
Here 36 of 39 minutes are spent idling/load/preparing and
I assume, most of the time is needed to store the snapshot.
Any idea to speed things up?
