This page describes the procedure for accessing and using our off-site backups. Only admins can do this -- if you want to get some file or directory back from the dead and are not an admin, please contact the hcoop-sysadmin list for assistance.

1. Backups of AFS Volumes

Using backup-manager:

backup-manager list
backup-manager list YYYY.MM.DD

1.2. Retrieving a backup

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/$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 db
cd db
cat ../databases.tar.gz.aescrypt | \
  ccrypt -cdk /etc/backup-encryption-key | \
  gunzip | \
  tar -xvzf -
