Hello all,
This is the user space side of btrfs send/receive.
You can apply them manually or use my git repo:
git://github.com/ablock84/btrfs-progs.git (branch send)
The branch is based on Hugo's integration-20120605 branch. I had to add a temporary
commit to fix a bug introduced in one of the strncpy/overflow patches that got into
btrfs-progs. This fix is not part of the btrfs send/receive patchset, but you'll
probably need it if you want to base on the integration branch. I hope this is not
required in the future when a new integration branch comes out.
Example usage:
Multiple snapshots at once:
btrfs send /mnt/snap[123] > snap123.btrfs
Single snapshot with manual parent:
btrfs send -p /mnt/snap3 /mnt/snap4 > snap4.btrfs
Receive both streams:
btrfs receive /mnt2 < snap123.btrfs
btrfs receive /mnt2 < snap4.btrfs
(Please give suggestions for a file extension)
Please read the kernel side email as well, especially the warnings!
Alex.
