Backups

osgeo1 (primary peer1 host)

    TODO: add in which time zone cron is running - Atlanta EST? 
     
     WISH: please don't run heavy backups during European day, but preferably 
     during Pacific Ocean day   (optimize backup time)


current cron jobs for backups

/etc/cron.d/backup.cron

backup script are in /root/scripts

backup_svn_incremental.sh runs every 3 hours and only dumps what has changed in the repository in the last three hours to /home/back/svn_backup/project/incremental

backup-svn_full.sh runs once a day at 1 am and does a 'svnadmin hotcopy' of the repository in /home/back/svn_backup/project/full. 14 copies of the repository are kept.

When adding a new svn repository, make sure to edit both the _full and _incremental scripts to add backups for your projects. You will also have to create the /home/back/svn_backup/project/{full,incremental} directories or the scripts will not work. rsync_back rsyncs www.osgeo.org/home/back with test.osgeo.net/home/back (the second PEER1 server)

Daily PEER1 Backup

PEER1 hosting service is doing daily tape backup of entire system using their SANS infrastructure.

  • This is a service we pay for on both osgeo1 and osgeo2. Do we need it on both?
  • At present it is backing up the complete file systems on both servers. We must provide them some direction as to the folders to include or exclude, so we maintain a reasonable sized backup. We then send them the list through their support ticket system.

Backup Folders / Files

Please list locations to be backed up here, preferably the same on both servers. Unless we feel we can drop the service on one of them.

  1. /etc - 10MB
  2. /var/www/trac - 550MB
  3. /root - 3MB
  4. /home/back/mailman - 1370MB

Mysql

MySQL is being backed up using MySQL-zrm

osgeo2 (test.osgeo.net)

  • Daily PEER1 Backup above also applies

download.osgeo.org

As noted in Download Server the contents of download.osgeo.org are rsync'ed to osgeo2.
