SVN Incremental and Full Backup - with Email Notification

To start of with lets do a Incremental back up for every commit and then lets look in to taking a full back for all our repositories. (Files Attached Below)

Incremental Backup.
SVN Incremental for every commit can be done using post-commit hook
this file is in REPOS_DIR/hooks/post-commit.tmpl you can copy it as post-commit
and change permissions.

$ cp post-commit.tmpl post-commit
$ chmod 755 post-commit

NOTE Important links:
For rsync refer this link
For mutt configuration refer this link.
For Running Crontab.
To Know about SVN backups you can go here.

Here is the information which needs to be in post-commit hook in SVN.

#
# PreDefined Information
#
REPOS="$1"
REV="$2"

#
# Change below parameters as Required.
#
LOCAL_BACKUP_PATH=/home/ahmed/SVNREPOS_TEST/test_backup_incremental
REMOTE_BACKUP_PATH=/home/ahmed/SVNREPOS_TEST/test_backup_full
LOCAL_MOUNT_BACKUP_PATH=/home/ahmed/SVNREPOS_TEST/test_backup_full
REMOTE_USER="backup_trusted_user"
REMOTE_SERVER="remote.server.com"
# Give Email Separated by Space( ) here.
EMAIL_GROUP="ahmed@gmail.com ahmed@groups.com"

#
# you need NOT TOUCH THIS !!
#
DATE=`date '+%d'-'%m'-'%Y'-'%H':'%M':'%S'`
BACKUP_FILENAME=commit-inc-ver\($REV\)-$DATE.bkp'.gz'
DIFF_FILENAME=diff-inc-ver\($REV\)-$DATE.gz


#
# Taking backup and rsync to a remote server.
#
svnadmin dump "$REPOS" --revision "$REV" --incremental | gzip > $LOCAL_BACKUP_PATH/$BACKUP_FILENAME
# rsync -avzh -e ssh $LOCAL_BACKUP_PATH  $REMOTE_USER@$REMOTE_SERVER:$REMOTE_BACKUP_PATH


#
# Can be backed-up on a Local mount Drive.
# Have commented - as we might not have a mount DRIVE
#
#cp $LOCAL_BACKUP_PATH/$BACKUP_FILENAME $LOCAL_MOUNT_BACKUP_PATH


#
# Now lets send mail to all the people - using mutt :)
#
svnlook diff $REPOS -r $REV | gzip > $DIFF_FILENAME
mutt -s "SVN Commit Complete - Back-Up for Version $REV" $EMAIL_GROUP < /dev/null -a $DIFF_FILENAME
rm $DIFF_FILENAME

Full SVN Back of all Repos.
Periodic SVN backup script which needs to be run using crontab.
Setting up an cron job is simple you can go through the above link.
Below script will take FULL backup for all the repositories within a svnroot directory.

#!/bin/sh
SVN_REPOSITORIES_ROOT_DIR="/home/ahmed/SVNREPOS_TEST/multiple_repos"
BACKUP_DIRECTORY="/home/ahmed/SVNREPOS_TEST/test_backup_full"
DATE=`date '+%d'-'%m'-'%Y'-'%H':'%M':'%S' `

for REPOSITORY in `ls -1 $SVN_REPOSITORIES_ROOT_DIR`
do
        #echo 'dumping repository: ' $REPOSITORY
        svnadmin dump $SVN_REPOSITORIES_ROOT_DIR/$REPOSITORY | gzip > $BACKUP_DIRECTORY/full-backup-$REPOSITORY-$DATE'.gz'
done
echo 'dumping repository: Successfull -' $DATE > /tmp/full-backup-$DATE.log

Now we are ready for some coding.
Scripts will take care of the rest :)

Installing Zabbix Version 2.4 Offline (Zabbix Server without Internet).

There might be situations where you have a remote/zabbix server which does not have internet connectivity, due to security or other reasons. So we create a custom repo on the remote/zabbix server so that we can install zabbix using rpms Here is how we are planning to do this. Download all the dependency rpms on a machine which has internet connection, using yum-downloadonly or repotrack . Transfer all the rpms to the remote server. Create a repo on the remote server. Update yum configuration. Install. NOTE: This method can be used to install any application, but here we have used zabbix as we had this requirement for a zabbix server. Download dependent rpms . On a machine which has internet connection install the package below. And download all the rpms . Make sure the system are similar (not required to be identical - At-least the OS should be of same version) mkdir /zabbix_rpms yum install yum-downloadonly Downloading all the rpms to location /zabbix_rpms/ ,...
