Backups

backup.osgeo.org (aka osgeo5, mirror)

This was the OSUOSL VM used for backups starting in 2010/04 and is now upgraded to dedicated hardware (very) early in 2014. It is used for Bacula backups of OSU OSL VMs and Rsync backups of the public space at "download.osgeo.org".

  • Admins: Frank Warmerdam (rsync), Martin Spott (bacula), Sandro Santilli (bacula)
  • access is via SAC shell group.
  • download.osgeo.org rsync mirroring runs nightly and is externally available at download2.osgeo.org.
  • /backup/bacula/ contains the Bacula storage device
  • /backup/rsync/ is for rsync backups
  • /backup/longterm/ is for long term backups of static material (ie conference web sites)
  • /backup/pgdump/ contains PostgreSQL dumps of the Bacula director database
  • /etc/bacula contains Bacula configuration, is under local git repo

osgeo3 & osgeo7

osgeo3 and osgeo7 are production LXD Hosts. Using the built in LXD scheduler snapshots of each container are done daily with a retention of 30 days. This means each container in case of disaster such as virus/exploit/serious misconfiguration can be restored to up to 30 days before.

In addition the latest snapshots of each container are made on a daily or weekly basis by osgeo4. osgeo4 serves as both a dev lxd host (e.g. it has wordpress-dev, wiki-dev, and tracsvn-dev) and a backup lxd host.

Smaller containers such as secure are snapshot nightly and pushed to osgeo4 using cronjob - /etc/cron.d/osgeo4-lxd-maint on osgeo4. Only one container snapshots of each is kept on osgeo4.

Larger containers such as repo (on osgeo3) and download and tracsvn on osgeo7 are snapshotted weekly and pushed to osgeo4. All backup containers are suffixed with -backup. So you will see on osgeo4 containers such as download-backup, grass-backup etc.

Right now a manual process - backups of key containers are made monthly and stored on backup.osgeo.org in the /backup/osgeo7_containers/image_backups/ folder. There is currently not enough space there to hold the download or repo backups. download is however rsync'ed to http://ftp.osuosl.org/pub/osgeo/download/ and folder in backup.osgeo.org.

download.osgeo.org

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

ProjectsVM

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.
