    Backup Slowdown and Windows VM Corruption Issues after Recent Update

    Hello everyone, I've been running a PVE and a Proxmox PBS server on high-scale machines in OVH's data center flawlessly for the past two years. However, after upgrading both products to their latest versions, I began encountering some peculiar issues with my backups. The first anomaly I noticed...

    Slow throughput on PBS running as a VM behind a FTTC connection

    I have a locally hosted lab setup consisting of PVE 7.4-15 which in turn is running a VM of PBS 3.0-1 called "backup.local". PVE is also running a few other VMs and LXCs. I have a relatively slow 60mbit/20mbit FTTC connection to my lab. I've tested this and verified that I'm getting close to...

    container backup is slow

    On my Large container the pbs takes 25 hours now. The same contaner with backuppc (incremental, rsync) takes about 90 minutes. Backing up a VM image is fast. (Non-incremental backuppc take 12 - 40 hours.) It seems pbs could use a feature where files with old atime/mtime would be skipped.

    Backup slowing down to a crawl

    I have this problem with a backup one one VM: the backup starts "ok" (not as fast as it could, but reasonable speed) but at some point slows down to almost no progress. Here are two logs: As you can see, there are sometimes "gaps" like in Log 1 between 59% and 60% it took more than 6000...
