Backups
backup.osgeo.org
This the OSUOSL VM used for backups starting in 2010/04. It is used for rsync backups of various things (download.osgeo.org, osgeo1, ...), and backula backups of OSU OSL VMs.
- Admins: Frank Warmerdam (rsync), Martin Spott (backula)
- access is via SAC shell group.
- download.osgeo.org rsync mirroring runs nightly and is externally available at download2.osgeo.org.
- /osgeo/backup/backula is for backula backups
- /osgeo/backup/rsync is for rsync backups
- /osgeo/longterm is for long term backups of static material (ie conference web sites)
Bacula
Configuration as of June, 2011
A Full copy is made every Sat. with incremental backups nightly.
This consists of the following directories:
File = /boot File = /etc File = /var/www File = /osgeo File = /var/lib/mysql File = /var/lib/postgresql File = /var/lib/dpkg File = /var/lib/aptitude/pkgstates
From each of the following machines:
- wiki,secure,web,webextra,backup,qgis,projects,adhoc
trac currently gets trac_backup.zip which is generated on demand
Administration
General configuration is managed in /etc/bacula/bacula-dir.conf.
To review the backups and perform a restore you can use the bconsole application:
sudo bconsole
Specific configuration of the file/tape storage is in the Storage director /etc/bacula/bacula-sd.conf
- Bacula uses the hard drive as a series of Tape drives.
- Each Volume is a predetermined size (~500MB currently), when a volume fills bacula makes the next one.
- Volumes older than a certain date or when volume increments have reach a configured maximum can be recycled into the available disk pool.
Recovery
- If you use bconsole to recover data bacula does the work of finding the files you want and pulling them out of the various volumes.
- Directory for recovered files is set in the bacula-dir.conf under:
Job {
Name = "RestoreFiles"
Type = Restore
Client = backup.osgeo.osuosl.org-fd
FileSet = "Full Set"
Storage = File
Pool = Default
Messages = Standard
Where = /tmp/bacula-restores
}
- Directions for how to restore
sudo bconsole *restore
Then follow the prompts, using the above linked guide to help find the files you want.

Bacula - we need details.
??? How does it work?
svn.osgeo.org
As noted in Subversion the subversion repository is mirrored using svn mirroring and does not need to be backed up otherwise.
