Mounting LZO backup files as a read-only FS

[alexpacio]

Hi everybody,
does anyone can tell me if is it possible to mount a Proxmox LZO backup file as a filesystem?
I'd need it to restore single files or folders instead of recovering an entire disk image.


Thanks

Could anybody help me?
It's very important.

That is possible.

Restore Image to a different ID and add your restored HDD to your running VM (perhaps you need to shutedown and start again). Then simply copy the files you need.

if you restore the backup to a new VM, you could also mount the disk image from that one via qemu-nbd

Yes but I can't mount the image before extracting the LZO compressed file. Imagine that I should have a 500GB lzo compressed backup image and i have to recover only one single file. Every server backup solution (as, for example, Acronis) lets you to recover quickly a single file without needing a complete restore of the image.

Any idea?

well LZO is a simple compression. however, the actual backup image format is .vma - a format that the proxmox guys invented (http://lists.gnu.org/archive/html/qemu-devel/2012-11/msg02126.html). Im afraid that this situation leads to there not being any way to interact with vma files apart from restoring them :/
