Hi,
Are you running the last version? Issue:
pveversion -v
Could you run a manual vzdump? For example:
-vzdump $VMID -dumpdir $Your-prefer-destination -bwlimit 0
Attach vzdump log file and version please.
Francisco.

Subject: [PVE-User] slow backup
Message-ID: <[email protected]>
Content-Type: text/plain; charset="utf-8"; Format="flowed"
Hello to all
I'm using 4xIntelAtom CPU 2558 @2,4GHz on the host
a backup storages are (1G) freenas nfs and local sata disk
So classic backup (vzdump) of 32G image takes about 1h ... the same
result to the nfs storage and to local sata disk
I tried changing bwlimit in vzdump.conf the result is allways the same
slow
But Clone VM takes less then 10 min
manual lzop backup of this image (nfs storage or sata disk) takes less
than 10' too ... tar runs same fast
So we cannot say tha CPU is not capable of doing archiving with
commpression
Why is backup so slow and what can I do to optimize it?
thank you very much in advance and
BR
Tonci //

I'm not sure what difference that would make for the container though.
With qemu it would be understandable, but with containers I don't immediately
see where that would go wrong.
It works fine on a single system anyway.
/dev/loop0 3.9G 8.0M 3.6G 1% /mnt/tmp
changed to
/dev/loop0 4.8G 8.0M 4.6G 1% /mnt/tmp
