For backing up the configurations and keeping copies of those for the previous 30 days and also allocating room for possible synced copies from other servers, minimum space requirements is 10GB. To accommodate for the synced copy of the repository that could go up to 2TB
===Data Retention===
* Removable drives will keep data up to 3 days old* Network synced drives/servers will keep data up to 30 days old
===Initial Setup===
This applies to any new server that will be backed up (this process could be scriptable become a script eventually)
* Create a user named "backup"
* Give that user certificate access through ssh (to and from) the other servers (in the backup group). Tutorials available [http://zenit.senecac.on.ca/wiki/index.php/OPS235_Lab_7 here]
* Also give cert access to the root of each server so that those can remote access to the "backup" user of other servers.
* Add a new lvm called archive that will be mounted as /archive on startup (add an entry to /etc/fstab). LVM tutorial available [http://zenit.senecac.on.ca/wiki/index.php/OPS235_Lab_4 here]
* Create the following directories and give "backup" write permission to those directories
/archive/repo-backup
/var/log/blaze-backup
* Add Create the following file and give "backup" write permission to that file and also add the hostname for the admin server (iraq) in that file (please see offered services section for other options) /etc/sysconfig/blaze* In the admin host, add the hostname in the buddyhost section in blaze and wildfire with a random syncpeer. (optional, please see offered services section for more options)
* Add the following entry to /etc/aliases (use proper email format):
blaze-wildfire: fedora-arm at senecacollege dot ca
20 2 * * * ADMHOST=$(cat /etc/sysconfig/blaze); BKU=backup; export ADMHOST BKU; scp $BKU@$ADMHOST:/usr/local/bin/blaze \
/usr/local/bin/; chown -R $BKU:$BKU /usr/local/bin/blaze; chmod 755 /usr/local/bin/blaze; /usr/local/bin/blaze
* If the server is going to be a reposync host then follow the first three steps to create a user account called apache and give it access to and from the repohost
===Scheduling===
* In Australia blaze runs at 02:20 AM UTC
* In Ireland blaze runs at 03:35 AM UTC
* In Scotland blaze runs at 12:50 AM EDT* In Romania blaze runs at 01:50 AM EDT* In Iraq blaze runs at 0108:30 AM EDT ===Offered/Backedup Servers/Services===* Please add the service type in the appropriate row in the "Define the names of the remote machines and services" section in each script** PostgreSQL Database Server (DBHOST)(Possibly one - Ireland)** Repository (REPOHOST) (Possibly one - Chile)** Server that has backup to removable drive capabilities (RBDHOST) (Chile or Ireland or Scotland)** Central Sync Server (SYNCHOST) (Iraq, Scotland and Romania)** Repository Backup (COPYREPOHOST) (Scotland Romania)** Sync Peer (BUDDYHOST) (All)** Custom Log and Mail Server (AGGREGHOST) (Iraq)** Administrator Host (ADMHOST) (Iraq, for now)** All related servers under blaze wildfire system (ALLSYS) (Australia Chile Hongkong Iraq Ireland Scotland Romania)
===Repo Sync===
* Repo sync process is done via rsync
ARM is still a developing technology and expectations are that The Fedora ARM Project at Seneca CDOT will be highly active for the next few years. Depending on the level of activity the backup strategy in place may become out of date in a matter of months or it may need to be supplemented with other solutions.
