Kopia keeps snapshotting certain shapshots on startup when it shouldn't

Support

My setup:

  • rpi kopia server (kopia-docker)
  • windows client (kopiaUI)
  • clients can’t change policies or delete snapshots.
  • some snapshots have different retention policy, otherwise identical policies
  • snapshots are set to run once a day on same time

3 out of 11 snapshots are constantly running when KopiaUI starts or when I disconnect → reconnect to server. I would like to understand why this is happening before wiping the snapshots and redoing them from the scratch to see if this gets fixed.

From server side (and client side), “policy show ‘user@host:path’” on those snapshots are identical to other snapshots that are not running on startup. There’s no difference on kopiaUI tasks log view to normal snapshot behavior.

I also tried with these policy changes on server side:

  • “–manual”
  • “–run-missed=false”

But no change. These specific 3 snapshots keep running on startup/reconnect.

Have I missed something else or is there some debug log stuff that could show more?

Gave Full rights to my client to test some stuffs quicker in kopiaUI and found out that it was somewhat related to “run missed snapshots on startup” and “ignore identical snapshots”.

I changed “ignore identical snapshots” from true to false. Then let let it do the startup snapshot behavior. After this it doesn’t seem to run on startup anymore.

Seems like having “ignore identical snapshots”=true and “run missed snapshots on startup”=true will cause it always snapshot on startup until it’s not identical. These problematic snapshots were the only ones that haven’t had any changes for days.

Ignore or not to ignore identical…
