making gzip backups compatible with rsync

[rpereyra]

Hi all

A question: backups made with compression gzip have the option "--rsyncable" enabled ?

This option makes gzip backups compatible with rsync.

Thanks to all proxmox developers !!

No, because the VMA format is not really rsyncable - so that would not really help.

You have to unpack the vma and then use rsync. Although, I personally do not recommend it. I had a lot of issues with really big files and the rsync-internal block detection algorithm. I ended up writing my own tool to COW-ware copy a file to a ZFS backup storage on a 4K block basis. This tool is so extremely fast (50 lines C code), it outperforms rsync by a factor or 100.

Ok, thanks a lot for this info.
