How do I create a backup account for a member?

The steps for creating a backup account for a member are:

1. Find a backup server with available space.
2. As root@BACKUP_SERVER do

   useradd -m -U MEMBER_NAME-sync
   

3. Create a backup directory for the MEMBER_NAME-sync user at /home/members/MEMBERNAME-sync/backups

   mkdir -p /home/members/MEMBER_NAME-sync/backups
   

4. Change ownership of that directory to the MEMBER_NAME-sync user.

   chown MEMBER_NAME-sync:MEMBER_NAME-sync /home/members/MEMBER_NAME-sync/backups
   

5. login as the MEMBER_NAME-sync user.

   su - MEMBER_NAME-sync
   

6. Create a symlink to the backup directory from the member's home directory.

   ln -s /home/members/MEMBER_NAME-sync/backups backups
   

7. Add the rsa key for the user or their monkeysphere/gpg user id to the /home/MEMBER-NAME-sync/.ssh/authorized_keys file or /home/MEMBER-NAME-sync/.monkeysphere/authorized_user_ids file respectively. Then run

    monkeysphere-authentication u MEMBER_NAME-sync
   

The member should now be able to ssh into the server with ssh MEMBER_NAME-sync@SERVER_NAME.mayfirst.org. If they can, then your task is complete!
