[PVE-User] backup takes so long to finish

[Gilberto Nunes]

Hum... At first moment, I thought I/O could being a trouble, since I was
ran backup in USB devices.
But now, I ran backup task on SAS disk! So performance and I/O is not an
issue here...
And, I can't shrink the file, because the entire disk is being used to all
databases as I described before...

If somebody else has any other advice, I will appreciate...
Thank you
