Hi Martin,
Any interest in adding functionality to the XS to back up and restore user data?
Including:
- stuff that has been posted on moodle
- XO backups
- registration information
but *not* stuff where deployments should always have a master copy elsewhere:
- activities from activity server
- OS images in xs-rsync
- system files
- ...
Here's an initial implementation, which can be used to create a
single-file compressed backup which can then be copied to an external
storage device.
Backup part has been tested, but not restore just yet. Needs a patch
to idmgr create_user too. What do you think?
