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.\r
\r
== Backups of AFS Volumes ==\r
\r
=== Getting access ===\r
\r
{{{\r
ssh FOO_admin@deleuze.hcoop.net\r
\r
aklog -c megacz.com\r
}}}\r
\r
=== Navigating the available backups ===\r
\r
{{{\r
cd /afs/megacz.com/hcoop-backup/\r
\r
cd $DESIRED_BACKUP_DATE\r
}}}\r
\r
=== Restoring the volume dump to a volume with a new name ===\r
\r
{{{\r
cat $VOLNAME.dump.bz2.aescrypt | \\r
  ccrypt -cdk /etc/backup-encryption-key | \\r
  bunzip2 | \\r
  vos restore deleuze /vicepa $VOLNAME.restored\r
}}}\r
\r
=== Mounting the newly restored volume onto the filesystem ===\r
\r
{{{\r
fs mkm /afs/hcoop.net/.old/tmp-mount $VOLNAME.restored\r
vos release old\r
}}}\r
\r
=== Restoring a particular file ===\r
\r
{{{\r
# examine /afs/hcoop.net/.old/tmp-mount\r
}}}\r
\r
=== Unmounting the restored volume ===\r
\r
{{{\r
fs rm /afs/hcoop.net/.old/tmp-mount\r
}}}\r
\r
=== Renaming the restored volume so it takes the place of the damaged/corrupted/erased volume ===\r
\r
Do this if you want to restore an entire volume.  This deletes the old volume and replaces it with the backup.\r
\r
{{{\r
vos remove $VOLNAME\r
vos rename $VOLNAME.restored $VOLNAME\r
}}}\r
\r
=== Removing the restored volume ===\r
\r
If you only wanted to restore a few files from the volume, you should remove the local copy of the backup volume when done.\r
\r
{{{\r
vos remove -id $VOLNAME.restored\r
}}}\r
\r
== Database Backups ==\r
\r
{{{\r
cat databases.tar.bz2.aescrypt | \\r
  ccrypt -cdk /etc/backup-encryption-key | \\r
  bunzip2 | \\r
  tar -xvzf -\r
}}}\r
