I do recommend running all the maintenance functions periodically - I run one each month (cycling through all four 3 times over the year). However, the defrag is the least useful (and if you use snapshots, it will reduce your free space).

Files disappearing is not a good sign (and the maintenance functions probably won't help). Do you have a backup of your data?
If you have snapshots enabled on the shares, you can see if the missing files are in the snapshots. You might also want to download the full log zip file, and look for btrfs and disk errors in system.log and kernel.log.
Hello, I am attaching the nas logos, I do not see any particular errors, but I am not an expert. Is it possible to understand if the files and folders have been accidentally deleted by an operator, or by a NAS error? About 70 folders have disappeared, almost all recovered from the previous day's snapshot, while a few were recovered from the August snapshot (so they disappeared a few months ago).
