That is a very interesting idea. I'll try some experiments with this. Many Thanks for the assistance:-) J. Hart On 03/27/2017 01:57 AM, Marat Khalili wrote: Just some consideration, since I've faced similar but no exactly same problem: use rsync, but create snapshots on target machine.

Just some consideration, since I've faced similar but no exactly same problem: use rsync, but create snapshots on target machine. Blind rsync will destroy deduplication of your snapshots and take huge amount of storage, so it's not a solution. But you can rsync --inline your snapshots in

backing up a file server with many subvolumes

2017-03-25 Thread J. Hart
I have a Btrfs filesystem on a backup server. This filesystem has a directory to hold backups for filesystems from remote machines. In this directory is a subdirectory for each machine. Under each machine subdirectory is one directory for each filesystem (ex /boot, /home, etc) on that
