=== Key Directories ===

* Create the "backups" directory and set permissions/ownership.

* Move to the "/etc" directory.

* Make a backup copy of the rsnapshot configuration file. Why? So that there is a reference just in case.

* Now using a favourite editor, open the "rnapshot.conf" file.

* Find the "SNAPSHOT ROOT DIRECTORY" section and change "snapshot_root" to path where the backups will be stored.

* Find the "BACKUP INTERVALS" section and change the line items. What does this all mean? The "#" character at the beginning of each line means the configuration line item will not be enabled. The "#" is know to set a line to be a "comment" line. The "interval daily" line will be active and 7 days of backups will be kept.

#interval weekly 4

#interval monthly 1

* Find the "logfile" line and change the line item. The rsnapshot log file will be kept under the "backups" directory.

* Find the "BACKUP POINTS / SCRIPTS" section. Add changes as seen below. This is the section that defines the "key directories" source that will be backed up. See the "owncloud/" at the end of each line? Remember the previous "green" server folder? This is where the ownCloud binaries and physical files will be stored.

* Next find the line "Backup OwnCloud MySQL database" change as shown below. This set the location where the ownCloud "database dump" backup will be kept. Also the line shows the execution path for the database backup program script file that performs the database backup.

* Save the "rsnapshot.conf" file and return to the command-line prompt.

* Copy database backup script to the "/usr/local/bin/".

:'''*''' - indicates rsnapshot version number

* Go to the "/usr/local/bin/" directory and set the script file permissions and ownership.

* Edit the "backup_mysql.sh" file.

* Find the line "backup the database" and add the line has shown below. This will be the command that will be issued to do the database backup. The database dump file will be called "owncloud_db.sql".

* Find the line "# make the backup readable only by root" and add the line shown below.

* Save the "backup_mysql.sh" file and return to the command-line prompt.

* Enter the following on the command-line to initiate the test.

* When the test completes the following should be displayed:

* If an error occurs the rsnapshot configuration file will need to be checked.

=== Backup ===

* The following command-line entry will perform the backup:

* The first time that rsnapshot runs could take sometime, each subsequent run should be quicker (depending on data changes).

* The following directories are created over time under the "backups" directory:

drwxr-xr-x 3 root root 4096 Feb 14 01:30 daily.1

drwxr-xr-x 3 root root 4096 Feb 13 01:30 daily.2

drwxr-xr-x 3 root root 4096 Feb 10 01:30 daily.5

drwxr-xr-x 3 root root 4096 Feb 9 01:30 daily.6

* As mentioned before, notice that the "daily.0" directory is the most recent backup version.

* Restore the ownCloud "config.php" file from the most recent backups with the following:

* Restore the ownCloud "apps" directory from the most recent backups with the following:

* Restore the ownCloud database from the most recent backups using the database dump file:

* Login to ownCloud using a normal user ID and test ownCloud functionality (i.e. sharing) and applications.

* If the prior testing was successful have other users test their ownCloud IDs.

* The restore of ownCloud is now completed.

* Before doing the "files" restore make sure that there is enough disk storage room.

* Enter the following "rsync" command to restore the "files" directory from the most recent backups. Depending on the amount of data stored the restore could take sometime.

* Restore the ownCloud "config.php" file from the most recent backups with the following:

* Restore the ownCloud "apps" directory from the most recent backups with the following:

* The following command-line entry will restore the ownCloud database from the most recent backups:

:'''NOTE:''' For all releases on or after ownCloud 6, change all instances of ''owncloud'' to ''owncloud6''.

===== Upgrade =====

* Restore the ownCloud "config.php" file from the most recent backups with the following:

* The following command-line entry will restore the ownCloud database from the most recent backups:

:'''NOTE:''' For all releases on or after ownCloud 6, change all instances of ''owncloud'' to ''owncloud<major release number> (i.e. owncloud6)''.

* A "root" user "cron job" could be created to perform backups at say "1:30 AM" everyday.

* Some system administrators will create a "nighttime backup script" cron job that is executed at say "1:30 AM" before a server is shutdown each night.

#!/bin/bash

# Night time operations: Backup and Shutdown

wall -n "$(date +%A) @ $(date +%T) system shutting down at scheduled time."

The backup tool is called, "oc-recover.sh". The recovery tool performs several different types of ownCloud recovery operations.
