Hi there.
Having a strange issue I’ve never encountered before. Prune jobs tend to last minutes on my backup, but the last one has been going for over 24 hours.
The log looks like this:
Options: [-log prune -storage NASBackup -keep 0:90 -keep 7:30 -keep 1:7 -a]
2020-11-16 22:58:26.297 INFO STORAGE_SET Storage set to gcd://xxxx

2020-11-16 23:02:39.126 WARN CHUNK_FOSSILIZE Chunk 5cc520ee4b62865147e513bcac9a91f181dfc03591b1f178d79228ea91837ae1 is already a fossil
The log is then full of the ‘WARN CHUNK_FOSSILIZE’ message, which is repeated for different chunks every few seconds and is currently at 7000 lines. The progress bar in the WebUI is blank.
Activity is shown on the GCD ‘activity’ tab, which indicates that the application is moving files around. I’m a little bit confused by this, mostly due to the lack of indication as to what is going on. Is there a problem with the prune process or the backup overall?
Thanks
Edit: Should also mention that my backup dataset is about 16TB
