QUESTION

btrfs send / receive on incremental folders that rotate

Asked 2021-Sep-28 at 06:36

I am using incremental backups using rsnapshot combined with a custom cmd_cp and cmd_rm to make use of btrfs snapshots, this procudes multiple daily btrfs subvolumes:

Answered 2021-Sep-28 at 06:36

I solved it! I created a bash script that syncs all snapshots with a date in the name to the remote server. The date is subtracted from btrfs subvolume show.

So daily.0 can become 2021-09-20-08-44-46 on the remote.

I sync backwards. daily.30 first. daily.0 last. This way I can pass the proper parent to btrfs send. E.g.: btrfs send -p daily.30 daily.29.

If the date named snapshot exists on the remote, I check with btrfs subvolume show whether it was properly synced. If not, I delete the remote subvolume/snapshot and re-sync. If it was already synced, I will skip the sync. A proper synced subvolume/snapshot has a Received UUID and readonly flag.

After syncing I compare all snapshot names of the remote to what was just synced. The difference will deleted (thus old snapshots).

I might share the code in the future when it's all been stable for a long run. For now I hope the above information will help others!

QUESTION

Hardening authorized_keys used in rsync backup

Asked 2021-Jul-15 at 08:36

I'm trying to make a rootfs backup from ServerA on to ServerB.
The connection is one way and is initialized from ServerB using rsnapshot.
I have made a backup account on ServerA and enabled paswordless sudo only for rsync

What I'm trying to accomplish:

Change the authorized_keys file on ServerA, so only the rsync command can be used via ssh.

On ServerB - /etc/rsnapshot.conf is setup to run rsync with the following args:

rsync_long_args --rsync-path="sudo rsync" --delete --numeric-ids --relative --delete-excluded

I have tried the following on ServerA:

from="ServerB",command="sudo rsync *" ssh-ed25519 SSH-KEY

But rsnapshot keeps crashing and giving IO error codes for rsync.

What am I missing here?

!! Problem Solved !!

Found out about rrsync --- /usr/share/doc/rsync/scripts/rrsync, copy it to wherever.

ServerA:authorized_keys --- command="sudo /usr/local/bin/rrsync -ro /backup"

Since I'm keeping a copy of the backups on ServerA, I might as well rsync from them instead of using rsnapshot on ServerB. (This was my initial idea, but it doesn't work since there are duplicate files because of links that rsnapshot creates, I ended up having rsnapshot running both on ServerA and ServerB, to save backups from ServerA to a localDir on ServerA and also make remote snapshots from ServerA to ServerB.)

Also changed the sudoers file on ServerA:
