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.
