Short version: I used this regex when restoring to a jail on the slocum server: !/\.zfs/snapshot/snapshot-for-backup/!/!

Background

Today I did this when setting up an ssh-key on a new host:

ssh-add -L > ~/.ssh/authorized_keys

Oh.

That should have been >>.

Restoring

During the Bacula restore, I need to change this path:

/usr/jails/mydev/.zfs/snapshot/snapshot-for-backup/usr/home/dan/.ssh/

to

/usr/jails/mydev/usr/home/dan/.ssh/

That is, I need to remove this from the path:

.zfs/snapshot/snapshot-for-backup

For background on this backup strategy using jails, ZFS snapshots, & Bacula, see this post about the script. As you will see, the described script has been modified and I’m doing things slightly differently. Why? See

Here is how you do that:

That worked. Got my auth’d keys back. Of course, this is also in Ansible…
