obackup
=======
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.
A robust file & database backup script that works for local and remote push or pull backups via ssh.
## About
OBackup is designed from ground to make the backup process as reliable as possible.
obackup is designed 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 in list is processed.
Before a task gets stopped, a first warning message is generated telling the task takes too long.

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.

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.
Obackup can execute local and remote commands before and after backup execution,

thus providing an easy way 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.

## Warning
Starting with Obackup 1.84RC4, the default behavior is modified.
Obackup now follows symlinks and treats them as the referent files / dirs, following symlinks even outside the backup root, which IMHO is more secure in terms of backups.
You may disable this behavior in the config file.

## Final words
Backup tasks aren't always reliable, connectivity loss, insufficient disk space, hacked servers with tons of unusefull stuff 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
you can successfully restore. 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.
