[Borgbackup] Backup taking very long - sometimes

[Samuel]

Dear borg-mailing-list,

I have a quite weird problem, I guess.

Borg runs on a regular daily basis and is working stable.
But the consumed cpu time varies between around 4 hours and 12-13 hours:

Aug 29 18:54:33 balkonien systemd[1]: borg.service: Consumed 13h 33min
17.260s CPU time.
Aug 30 16:26:14 balkonien systemd[1]: borg.service: Consumed 11h 31min
14.142s CPU time.
Aug 31 22:10:19 balkonien systemd[1]: borg.service: Consumed 11h 52min
34.410s CPU time.
Sep 01 07:37:53 balkonien systemd[1]: borg.service: Consumed 4h 13min
21.085s CPU time.
Sep 02 15:30:09 balkonien systemd[1]: borg.service: Consumed 10h 45min
23.284s CPU time.
Sep 03 21:44:20 balkonien systemd[1]: borg.service: Consumed 11h 31min
47.892s CPU time.
Sep 04 06:30:58 balkonien systemd[1]: borg.service: Consumed 3h 58min
39.703s CPU time.


I don't see the cause for this behaviour.

Can you help me investigate this?

Thank you very much.
Samuel
