TRIUMF Grid Back-ups
A complete backup system is not yet in place for our prototype cluster. To ensure that all critical file systems are backed up for now we
do the following:
- Two nodes - lcfg and lcgui01 - are backed up via TRIUMF's amanda setup. /etc and /home are backed up. Additionally /var is backed up for lcfg.
- Once a week, on saturday evening, the script /root/bin/doBackup runs from lcfg. This script cycles through all nodes and backs up the following trees, storing the tarballs at /home/backups/YYYY_MM_DD/ on lcfg:
- /etc
- /root
- /opt/lcg/yaim
- /var/spool
- /var/log
- /opt/globus/var (except lcggiis01)
- /opt/edg/var (except lcfg and condorg)
Additionally specific nodes have these trees backed up:
| host | tree |
|---|---|
| lcgui01, lcgce02, condorg |
/opt/condor |
| lcfg | /var/www, /var/lib/ganglia |
| lcggiis01, lcgce01, lcgce02 |
/var/lib/mysql |
| sc4tr | /var/lib/lgsql, /opt/pnfsdb |
| sc5tr | /var/tmp/glite-url-copy-sc3 |
- Additionally on sc4tr cyclic backups are run as /root/bin/backup_pnfsdb every hour for database systems mysql, pgsql and pnfsdb. Backup files are created in /home/backups/pnfsdb/?/?? where ?/?? corresponds to dayofweek/hourofday. Hence the files are eventually overwritten once a week. As well the entire tree is rsync-ed to sc1tr:/home/backups/pnfsdb/
