1. Backups of AFS Volumes
1.1. Navigating the available backups
Using backup-manager:
backup-manager list backup-manager list YYYY.MM.DD
1.2. Retrieving a backup
(NOTE: $VOLNAME is not simply username, it is <db|mail|user>.USERNAME)
Using backup-manager:
backup-manager get YYYY.MM.DD $VOLNAME.dump.gz.aescrypt
1.3. Restoring the volume dump to a volume with a new name
Using backup-manager:
backup-manager restore YYYY.MM.DD $VOLNAME.dump.gz.aescrypt $VOLNAME.restored
Manually:
cat /vicepa/hcoop-backups/restored/YYYY.MM.DD-$VOLNAME.dump.gz.aescrypt | \ ccrypt -cdk /etc/backup-encryption-key | \ gunzip | \ vos restore deleuze /vicepa $VOLNAME.restored
1.4. Mounting the newly restored volume onto the filesystem
fs mkm /afs/hcoop.net/.old/tmp-mount $VOLNAME.restored vos release old
1.5. Restoring a particular file
# examine /afs/hcoop.net/.old/tmp-mount
1.6. Unmounting the restored volume
fs rm /afs/hcoop.net/.old/tmp-mount vos release old
1.7. 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
1.8. 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 -id $VOLNAME.restored
2. Database Backups
cd /vicepa/hcoop-backups/restored mkdir YYYY.MM.DD-db cd YYYY.MM.DD-db cat ../YYYY.MM.DD-databases.tar.gz.aescrypt | \ ccrypt -cdk /etc/backup-encryption-key | \ gunzip | \ tar -xvzf -
