Backups

backup.osgeo.org (aka osgeo5, mirror)

This was the OSUOSL VM used for backups starting in 2010/04 and upgraded to dedicated hardware (very) early in 2014. It is used for Bacula backups of osgeo6.

• 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

OS installation

• Create an empty partition at the beginning of every hard drive, use "Reserved BIOS boot area" on GPT-partitioned disks (typical with 2 GByte disks or bigger) or just "Unused" on DOS-type partition tables. By tradition I reserve 10 MByte on each disk, maybe 1 MByte would be sufficient as well, but these 9 MByte of difference don't cost that much and you're on the safe side ....
• Create a second partition on every disk - for use by MD - allocating all the remaining disk space
• MD RAID5 over all the 'second' partitions for use by LVM - 8 TB usable space
• LVM volume group on top of the MD physical volume
• Volumes
  • "boot" (256 MByte, Ext2, /boot/),
  • "root" (20 GByte, XFS, /root/),
  • "swap" (8 GByte),
  • "var" (20 GByte, XFS, /var/)
• Install the base operating system, don't forget to set up SSH ;-)
• Volumes
  • "backup" (2 TByte, XFS, /backup/),
  • "mirror" (1 TByte, XFS, /mirror/)

osgeo3 & osgeo7 & osgeo8 & osgeo9

osgeo3, osgeo7, osgeo8, osgeo9 are production LXD Hosts. osgeo8 and osgeo9 are donated by OSMF. All servers are are backed up to osgeo4, except for download on osgeo7. These are done nightly or weekly based on frequency of use and size. The scripts for these are in ansible under osgeo4 deployment and setup to run as a cronjob on osgeo4. download.osgeo.org is replicated to osgeo8 accessible via download8.osgeo.org.

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 that change frequently 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 and stored on backup.osgeo.org in the /backup/osgeo7_containers/image_backups/ folder. There is currently not enough space there to hold other backups. download is however rsync'ed to http://ftp.osuosl.org/pub/osgeo/download/ .

download.osgeo.org

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

svn.osgeo.org

As noted in Subversion the subversion repository is mirrored using svn mirroring and does not need to be backed up otherwise.
