Hi,
I'm using PBS version 4.1.4 with a compatible S3 datastore (Dell ECS). I'm currently running backups, and I've noticed the following warnings.
Backup verification is very slow. I set the job to once a week, and it's been verifying for two days now.
VM restore, I tried restoring the files and the download works correctly, but I get many warnings on my keyboard (I'm attaching a file) like this:
found empty chunk

Hi,
while this warning is benign I will see that we do silence it or at least change it to an info level instead. This happens when an already known but evicted chunk is being re-inserted in the local datastore cache for datastores backed by an S3 endpoint, which is normal operation for S3 stores, not for regular ones.
 
CIAO,
Sebbene questo avviso sia benigno, vedrò di silenziarlo o almeno di modificarlo a livello informativo. Questo accade quando un blocco già noto ma rimosso viene reinserito nella cache del datastore locale per i datastore supportati da un endpoint S3, operazione normale per gli store S3, non per quelli standard.
Thank you so much for your reply. It will be fixed in a future update. I actually had a moment, since it wasn't a particularly severe warning. Honestly, the problem arose while managing monitoring and having to deal with these warnings that were hindering my monitoring. So, I'm waiting for a resolution with the next pbs or pve updates?
