History

13.09.2015

backup moved to /mnt/backup

14.09.2015

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

15.09.2015

Ran badblocks command. Did not find errors.

sudo badblocks -v /dev/xvdf > /home/alvaro/badblocks

16.09.2015

Remounted /mnt/backup. /var/backups now points to /mnt/backup

sudo umount /mnt/backup
sudo mount -t ext4 -o remount,rw /dev/xvdf /mnt/backup

17.09.2015

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

01.10.2015

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

09.10.2015

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.

16.10.2015

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.

19.10.2015

Test failed. Reverted.

21.12.2015

NEW TEST. Since the network was reconfigured by WF. Seems to work.

CURRENTLY TESTING

Changes below have been reverted, as there were problems with Xen.

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
