This page describes the procedure for accessing and using our off-site backups.
1. Mounting the backup volume
1.1. Getting access
ssh FOO_admin@deleuze.hcoop.net aklog -c megacz.com
1.2. Navigating the available backups
cd /afs/megacz.com/hcoop-backup/ cd $DESIRED_BACKUP_DATE
1.3. Restoring the volume dump to a volume with a new name
cat $VOLNAME.dump.bz2.aescrypt | \ ccrypt -cdk /etc/backup-encryption-key | \ bunzip2 | \ vos restore deleuze /vicepa $VOLNAME.restored
1.4. Mounting the newly restored volume onto the filesystem
fs mkm /afs/hcoop.net/.../tmp-mount $VOLNAME.restored
2. Restoring a particular file
# examine /afs/hcoop.net/.../tmp-mount
3. Unmounting the restored volume
fs rm /afs/hcoop.net/.../tmp-mount
4. Renaming the restored volume so it takes the place of the damaged/corrupted/erased volume
Do this if you want to restore an entire volume. This deletes the old volume and replaces it with the backup.
vos remove $VOLNAME vos rename $VOLNAME.restored $VOLNAME
5. Removing the restored volume
If you only wanted to restore a few files from the volume, you should remove the local copy of the backup volume when done.
vos remove $VOLNAME.restored
