SAC:Backups

= Backups =

backup.osgeo.org
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

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
 * Create an MD RAID5 over all the 'second' partitions for use by LVM
 * Create a LVM volume group on top of the MD physical volume
 * Create 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 ;-)
 * Add volumes "backup" (2 TByte, XFS, /backup/), "mirror" (1 TByte, XFS, /mirror/)

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.
