There is some very valuable information here but is there any decent documentation for the maintenance commands? In particular, what do each of `snapshot verify`, `content verify` and `maintenance run` do? I would like to add these verification options to my [kopia monitoring tool](https://github.com/ekutner/kopia-mon) but I’m not sure which one to use, or maybe they should all be used? Following the discussion in this thread I ran “content verify --verify-files-percent=10” and got quite a lot of errors (\>20) so I’m guessing my repository is in a bad shape. However, I don’t understand how it could happen, because I’m backing up to a directly attached internal hard drive, which doesn’t report any errors. I tried running “snapshot verify --verify-files-percent=10” and it didn’t report any errors, so I’m trying again on 100% but either way, since I I don’t know what it actually does, I don’t know what to make of these findings or how to fix them. As a side note it’s also worth mentioning that this verification process is unreasonably slow. It has been running for more than 2 hours now and only processed about 6% of the objects. Any help will be greatly appreciated. --- _[View the full topic](https://kopia.discourse.group/t/does-kopiaui-not-verify-snapshots/3778)._
