 obackup
 =======

-A small robust file & database backup script tailored for multiple virtualhost backups locally or remotely via ssh.
-Yet it is very versatile and actually works for a lot of backup tasks.
+A small robust file & database backup script for local to local or remote to local backups via ssh.
+Works especially well for multiple virtualhost backups with 'backup divide task' functionnality.

 ## About

 OBackup is designed from ground to make the backup process as reliable as possible.
 It divides the whole backup process into tasks, allowing each task to execute for a certain amount of time.
-If a task doesn't finish in time, it's stopped and the next task is processed.
+If a task doesn't finish in time, it's stopped and the next task in list is processed.
 Before a task gets stopped, a first warning message is generated telling the task takes too long.
-Every action gets logged, and at the end of the backup process, if there was a warning,
-a stopped task or an error an alert email will be sent.
+Every action gets logged, and if a warning has been generated, a task gets stopped or an error happens, an alert email will be sent.

 Remote backups are initiated from the backup server instead of the production server, so hacked servers won't get ssh access to the backup server.

-OBackup can enumerate and backup all MariaDB / MySQL databases present on a server
+OBackup can enumerate and backup all MariaDB / MySQL databases present on a server.
 It can also enumarate all subdirectories of a given path and process them as separate tasks (usefull for multiple vhosts).
-It will do several checks before launching a backup like execution checks, dryruns,
-checking backup size and available local disk space.
+It will do several checks before launching a backup like execution checks, dryruns, checking backup size and available local disk space.

-Obackup will work well to backup to a snapshot aware filesystem like ZFS or btrfs.
-In case you don't work with one of these, it may also rotate backups for you.

-Obackup can execute local and remote commands before and after backup execution, thus providing possibilites to handle snapshots (see https://github.com/deajan/zsnap for a zfs snapshot management script).

+It may also rotate backups for you.

 As of today, obackup has been tested successfully on RHEL / CentOS 5, CentOS 6, Debian 6.0.7 and Linux Mint 14.
 Currently, Obackup also runs on FreeBSD and Windows MSYS environment, altough it is not fully tested yet.

 ## Installation

 You can download the latest obackup script from authors website.
-You may also clone this git which will maybe have some more recent build.
+You may also clone the following git which will maybe have some more recent builds.

    $ git clone git://github.com/deajan/obackup.git
    $ chmod +x ./obackup.sh

 Obackup needs to run with bash shell, using any other shell will most probably fail.  
-Once you have grabbed a copy of Obackup, just edit the config file with your favorite text editor to setup your environment and you're ready to run. A detailled documentation can be found in the DOCUMENTATION.md file.
-You can run multiple instances of obackup scripts with different backup environments. Just create another configuration file, edit it's environment and you're ready to run concurrently.

 Performing remote backups requires you to create RSA private / public key pair. Please see documentation for further information.
 Performing mysql backups requires to create a mysql user with SELECT rights on all databases. Please see documentation for further information.
-Performing backup with SUDO_EXEC option requires to configure sudoers file to allow some commands without password. Keep in mind that running backup as superuser might be a security risk. You should generally prefer a read only enabled user. Please see documentation for further information.

 ## Usage

 MariaDB / MySQL backups are consistent because dumps are done with the --single-transaction option.
-File backups can be done directly if data won't change while a backup is going on (generally true on vhosts), but backing up a snapshot of the actual data is preferable as it will stay consistent. LVM, zfs or btrfs snapshots will do fine.

-You may try your setup by specifying the "--dry" parameter which will run a simulation of what will be done.
+You may try your setup by specifying the "--dry" parameter which will run a simulation of what will be done. Specifying "--verbose" will also list any command
+that's actually launched and it's result.

    $ ./obackup.sh path/to/backup.conf --dry
    $ ./obackup.sh path/to/backup.conf
+    $ ./obackup.sh path/to/backup.conf --silent
+	

 One you're happy with a test run, you may run obackup as a cron task with the "--silent" parameter so output will not be written to stdout.
-All backup activity is logged to "/var/log/obackup_backupname.log".
+All backup activity is logged to "/var/log/obackup_backupname.log" or current directory if /var/log is not writable.

 ## Final words

-Backup tasks aren't always reliable, connectivity loss, insufficient disk space, hacked computers with tons of mangas to backup... Anything can happen. Obackup will sent your a warning email for every issue it can handle.
-Nevertheless, you should assure yourself that your backup tasks will get done the way you meant it. Also, a backup isn't valuable until you're sure it's restoration will be a success. Try to restore your backups to check whether everything is okay. Backups will keep file permissions and owners, but may loose ACLs if destination file system won't handle them.
