Perfect,<br>
<br>
I will have another question. Does CRIU will be package inside the
proxmox 4.0 to enable checkpoint of LXC containers ? Does you have
any plan to support differential backup with vzdump too (today
vzdump require 2 more time space on hard disk to be able to backup a
container on vzdump) ?<br>
<br>
Thanks<br>

With qemu it would be understandable, but with containers I don't immediately

but now, resize2fs is not working inside the container.

I'll try to find some infos about this.

Force the loop driver to reread the size of the file associated with the
specified loop device.
Worth a try?

Offline should be possible.
For block device (zfs, rbd,..) I think we can resize online. (and snapshot
too)

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