Hi Guys,
i am fiddeling around with Backups on my cluster.

I have KVM VM's running on a SAN and local openvz VM's

I created a cifs share on the netapp and mounted it on every node of the cluster as /backup.

Then i added a store (Directory /backup) using this mounted share.

i configured a backup for a KVM machine and choosed "snapshot" as Modus.
The VM is a Windows 7

The Log tells me:
Code:

I thought it is possible to backup a running kvm machine when using a ISCSI/LVM store? isn't it possible to dump into Snapshot with my config?


The openvz VM is dumped as a snapshot to the share as it should.

BUT: I did not get any EMAIL, even though i configured it in the Backup.

Where do i have to check the SMTP settings?

Click to expand...

should work, how did you install Proxmox VE, from ISO?
do you have enough free space in the volume?

Code: 
pvdisplay

SMTP setup: is done automatically during installation (from ISO), to change manually see /etc/postfix/
 
Why does it write into '/var/lib/vz/vzdump-qemu-101-2010_01_14-13_33_02.tgz'? Seems you did not specify the backup storage for the backup job?
 
ok i verified the storage and now it seems to work:

And for Emails:

i did a dpkg-reconfigure postfix and told postfix to be a satellite system that uses a mailserver as relay and now the mails are delivered.

Thanks a lot.
