<br>
is there any way to speed up PVE Backups?<br>
<br>
I'm trying to evaluate the optimal method doing backups but they took<br>
very long.<br>
<br>
I'm trying to use vzdump on top of nfs on top of btrfs using zlib<br>
compression.<br>
<br>
The target FS it totally idle but the backup is running at a very low speed.<br>
<br>
The output after 15 minutes is:<br>
INFO: starting new backup job: vzdump 132 --remove 0 --mode snapshot<br>
--storage vmbackup --node 1234<br>
