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/)

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.
