====== Backup Scheme ======

^Linux Drive^Partition^Usage^
|/dev/sda|sda1|unknown|
|/dev/sdb|sdb1|Linux OS|
|/dev/sdc|sdc1|/var/nas|
|/dev/sdd|sdd1|/var/archive (750Gb Hard Drive)|

Backups are done from my main PC (and possibly other places) to ''/var/nas/backup''. Periodically, this is copied to an offsite backup drive, which is mounted:

<code bash>
sudo mount /dev/sdd1 /mnt/offsitebackup
</code>

There is also **archive** content at /var/archive, which is sole copies of things that are only nice-to-have. They aren't backup up to offsite because it is not vital that these be retained.

Then we rsync like this, available as rsyncToOffsiteMedia in /home/dwheele on Joshua (it won't run from /var/nas because execute is not included in /etc/fstab):

<code bash>
#!/bin/bash
rsync -a /var/nas/backup/ /mnt/offsitebackup/backup
</code>

Note the source directory has a trailing slash. This means to copy the contents of this directory, and to not create a backup directory inside of the source directory.


To disconnect:

<code bash>
sudo umount /dev/sdd1
</code>

Then the offsite drive can be moved off site.
