Backup


The ever increasing volumes of data kept on home networks, much of which would be irreplaceable in the event of accidental erasure or catastrophic component failure should be frightening.  


Everyone in the IT industry knows that these things happen and considerable amounts of money and resources are invested in ensuring that critical data will be recoverable after an event.  


However most home users including many IT professionals skate on thin ice when it comes to running a comprehensive backup regime.  Apart from anything backup kit can cost a lot and is not exciting, lacks flashing lights, buttons, bells and whistles.  These are significant factors when spending ones own money!


Having lots of older kit around I decided to try and automate a solution here at minimum cost.

Bacula


We have implemented a disk to disk backup regime here based on the Open Source enterprise capable Bacula package and a ‘dedicated’ OpenSuse server with several Terabytes of Raid 1 (Mirrored) disk.


The server runs a conventional weekly/daily, full/incremental backup cycle of the primary server and other devices.  


This server is connected to the mains through a ZWave appliance module and it is woken up by the primary server each night to run the backups.
