Backup Solutions

Hello everybody,
I would like to know how do you handle incremental backups of your VMs.

With VMware we use to install a dedicated VM which handles hot incremental backups overnight using CBT and writing everything on a NAS, so there's no agent installed individually on each VM. Is there any similar solutions (possibily easy to setup and maintain) to use with proxmox, which would perform full/incremental backups of VMS at hypervisor-side?

I read something on this forum about LVM snapshots....
Any thoughts?

Thanks,
Michele

My setting are LZO & Stop.

Unfortunately, the speeds are painfully slow considering I'm on a GB network with new NFS (Synology 415+), 2x PCIe Intel GB nics, CAT6 cables, Netgear Smart Switch, 803.2ad enabled, mtu 9000...

Hello Michele,

I use LVM snapshots with storebackup since a few years for incremental backups without problems..

If you are looking for something newer to backup LVM snapshots incrementally I would take a look at zbackup or bup. But bup was a bit slow at my first test.

What about use some imaging tool (eg. Acronis) on the hypervisor?
Restoring a virtual machine from a backup should be easy as replacing its own disk file, isn't it?

qemu incremental backup should come for qemu 2.4.

(so maybe proxmox 4.0 or 4.1)

Proxmox 4.0 is out. Are there any improvements with backups (eg. incremental) ?

I'm still looking for a reliable solution which allows to perform VMs' disk images without requiring an agent installed on each, and which supports incremental/differential tasks as well, in order to save storage space. In addition it would be great if it would not depend on the underlying filesystem used for store vm images (ZFS, LVM, ...) so that will be suitable for use with any environment. Possibility to mount the backup image is a plus, but really appreciated.

Does a solution like this exists on earth for proxmox?

Thanks

qemu 2.4 have basic support for incremental backup, but it's not working across live migration or if vm has been stopped. (in this case a new full backup is needed)

I think it's be ready for qemu 2.5 or 2.6. (so proxmox 4.1 or 4.2)

(and it's work with any storage, withtout snapshot).
