[Box Backup] How to move store to new machine

[E.W. Peter Jalajas]

Hi Chris,

Funny to see myself typing this because I really have no idea, but I
think the _bbstored user and PAM are fine.  He is odd because he is
created without a password (as instructed), which I think is secure
because no one can become him except by doing sudo su _bbstored (which
is simple to do when needed). 

Re the permissions, I have no idea either except for the netcat tar
deal I did.  Maybe this confirms that I'm ok:
drwxr-xr-x   2 _bbstored users    4096 Mar  1 16:44 0e
drwxr-xr-x   2 _bbstored users    4096 May 16 12:55 0f
The old directories has the same perms as the new ones.

I'm a little nervous at the moment about so many new files being
created.  
-rw-r--r--   1 _bbstored users     135 Feb  9 12:14 o23.rfw
-rw-r--r--   1 _bbstored users   67015 May 16 12:49 o24.rfw
-rw-r--r--   1 _bbstored users     135 Feb  9 12:25 o28.rfw
-rw-r--r--   1 _bbstored users   58343 May 16 12:49 o29.rfw
-rw-r--r--   1 _bbstored users     135 Feb  9 12:35 o2d.rfw
-rw-r--r--   1 _bbstored users   38055 May 16 12:49 o2e.rfw
-rw-r--r--   1 _bbstored users     135 Feb  9 12:37 o30.rfw
-rw-r--r--   1 _bbstored users    9703 May 16 12:50 o31.rfw

user@new:~$ date ; du -s /media/bu2/backup/<acctno> ; find
/media/bu2/backup/<acctno> -type f | wc -l

user@new:~$ date ; du -s /media/bu2/backup/<acctno>; find

(this redaction/obfuscation thing I'm doing is a big pain in the neck
waste of time, isn't it?)

And I can't see any files that are dated after Friday... I'll have to
wait and see because of the weekend and the flooding we had yesterday
Monday, maybe they didn't create any files yesterday...  Heck, maybe
this all fixed something that was broken before.

I didn't, but should have, run 
/usr/local/bin/bbstoreaccounts check <acctno> fix
on all my accounts before I did the tar netcat.  That should be added
to the wiki.  (I think I have at least 3 wiki edits I need to make
now.)

user@new:~$ grep -i user /etc/box/bbstored.conf
        User = _bbstored
which was set during the server config with 
/usr/local/bin/bbstored-config /etc/box hostname _bbstored 
I believe. http://boxbackup.hostworks.ca/index.php/Configuring_a_server

Thanks again,
Pete
