moobk is a CoW filesystem backup tool. Currently only btrfs/zfs are supported.

WIP

moobk is still under developing and need more tests. It will not be considered as stable before v0.1.0.

Install

• go get github.com/raohwork/moobk if you have golang tools installed. Or
• Download from release page on GitHub.

Make sure that fs-tools like btrfs or zfs are accessible. See "moobk driver" for detail.

Synopsis

Run "moobk help", "moobk help driver", "moobk help repo" to see online docs.

# show usage
moobk help

# show usage of a command (like snap)
moobk help snap

# take a snapshot of /.droot/@root at localhost, save it to /.droot/snapshot/@root-timestamp at localhost
moobk snap local:///.droot/snapshot /.droot/@root

# take a snapshot of /.droot/@root at remote using ssh, save it to /.droot/snapshot/@root-timestamp at remote
# you might have to install moobk on remote host and allow root login with pubkey
moobk c ssh:///.droot/snapshot /.droot/@root

# list all recognized snapshots in /.droot/snapshot at localhost
moobk list local:///.droot/snapshot

# list all recognized snapshots in /data/backup at remote host using ssh
moobk l ssh://user@ip:port/data/backup

# list all recognized snapshots in /data/backup at remote host using ssh
# you might have to install moobk on remote host and allow passwordless sudo
moobk ls ssh+sudo://user@ip:port/data/backup

# delete synchronized snapshots in /.droot/snapshot at localhost, according to what exists at remote host
moobk purge local:///.droot/snapshot ssh+sudo://user@ip:port/data/backup

# same as above, but reserves up to 2 more snapshot (which means 3 total)
moobk d local:///.droot/snapshot ssh+sudo://user@ip:port/data/backup 2

# same as above, but reserves up to 2 days ago from now (also supports h/w/m for hour/week/month)
moobk purge local:///.droot/snapshot ssh+sudo://user@ip:port/data/backup 2d

# transfer snapshots from localhost to remote
moobk transfer local:///.droot/snapshot ssh+sudo://user@ip:port/data/backup

# transfer matching snapshots from localhost to remote
moobk t local:///.droot/snapshot -name rootfs ssh+sudo://user@ip:port/data/backup

# transfer snapshots from remote to localhost
moobk t ssh+sudo://user@ip:port/data/backup local:///.droot/snapshot

# transfer snapshot from one remote machine to another, with ssh options
# A and B are not directly connected, so it doubles network usage on local machine.
moobk t ssh+sudo://user@1.2.3.4:port/data/backup?ssh_4 ssh+sudo://user@5.6.7.8:port/data/backup?ssh_4

WARNING

• It does not know source path from snapshot, you have to remember it by yourself. Write simple shell script for automation is suggested.
• Snapshot naming scheme is fixed.
• It compares snapshots only by their name and timestamp.
