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 RecoveryJob

osgeo1 (primary peer1 host)

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.
