Backups can now be saved to a backup drive. The drive in mounted on /mnt/backup. Previously, backups were saved to /mnt/dump/var/backups. Note: /var/backups is a link to /mnt/dump/var/backups.

Backup of /etc/backupscripts/ in /etc/backupscripts.20150911

Set DBBAKDIR_ROOT="/mnt/backup" in these scripts in /etc/backupscripts:

• daily_bak_entry.sh
• daily_bak_master.sh

The following scripts are unchanged, as they take their paths from daily_bak_master.sh:

• daily_bak_mysql.sh
• daily_bak_svn.sh
• daily_bak_settings.sh
• daily_bak_wiki_media.sh

Copied everything from /mnt/dump/var/backups into /mnt/backup, keeping owners, permissions and timestamps

sudo cp -rp /mnt/dump/var/backups/DAILY /mnt/backup
sudo cp -rp /mnt/dump/var/backups/WEEKLY /mnt/backup
sudo cp -rp /mnt/dump/var/backups/MONTHLY /mnt/backup
sudo cp -p /mnt/dump/var/backups/* /mnt/backup

alternative: copy just the directory structure

sudo find -type d -links 2 -exec mkdir -p "/mnt/backup/{}" \;

/var/backups now points to /mnt/backup, as the scripts which create apt-, dpkg-, passwd-, group-, gshadow- and shadow-backups have hard coded the path to /var/backups.

Cron has to be restarted to reload files which are not in /etc/cron.d

sudo service cron restart

REVERTED as /mnt/backup was re-mounted read-only due to errors

After checking with the system administrator of MfN, remounted /mnt/backup. /var/backups now points to /mnt/backup

REVERTED. All changes have been reverted, as there are problems with the integration of the backup partition and Xen. As I have no access to the virtual machine's hypervisor and the system administrator of MfN could not solve the problem, I have reverted all the changes to the previous situation. So backups are being made, but they are on the same machine as the operating system.

NEW TEST. I will try to run the backups to the new partition during the weekend. The partition is now correctly mounted as read-write. If the backups fail again, I will definitely stop trying.

Test failed. Reverted.

Works since the network was reconfigured by WF.
