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,trac,webextra,backup,qgis,projects,adhoc

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

download.osgeo.org

As noted in Download Server the contents of download.osgeo.org are rsync'ed to osgeo2.

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.
