I have a scheduled backup in our Linux Artifactory instance to back up our
content to a CIFS-mounted network directory. I previously backed it up to
local disk on the same server, but it didn't make much sense to back up to
the same disk the original content was on as a disk failure would wipe out
both.
Anyway, what I'm seeing is disappointing performance, where it is taking
several hours to do an incremental backup. The original backup (with no
data in the target network directory) took 445 minutes, and the incremental
I just ran now took
Back when I had things running to back up to the same disk as the
repository was on it was still taking about 50 minutes to do an
incremental, with no significant changes from one backup to the next. This
is with about 80 gigs of data and 55000 "nodes" to be backed up. The
documentation indicates that incremental backups should be really quick
(assuming that not much has changed from the previous run), but my data
indicates otherwise.
Is there some other background processing that's going on in the
incremental backup (or is it actually re-copying every file even in
incremental mode), or is Artifactory computing some sort of checksum for
each target file that's taking so long to run even in incremental backups?
I note that the java process is using cpu cycles, so it is doing
*something* processor-intensive during the backup, I just don't know what
it is.
A separate Artifactory server (also on Linux) at a different site shows
similar behavior of non-quick incremental backups, so it's not isolated to
this specific box.
Just curious if others are seeing this same sort of behavior with
incremental backups taking a long time when the documentation indicates
that they should be fast. If it matters, we're running version 3.0.0, rev
30001.
Thanks!
