QuestionKDE / Git Prompted Review of Personal Backup Strategy Pin

I do have one but something about it has been bothering me for a while.

Since, apart from the obviously good reasons for having backups, any failure to carefully guard pictures and videos of our wee little man will cause me to involuntarily lose body parts courtesy of my good lady I've had everything 'backed up' for the last couple of years, it even survived moving country.

The KDE story finally prompted me to kick-off the process and then I hit a problem. Since backup didn't seem to fit into any of the other forums I've dropped it in here and also here since it seems to be of general interest to most. Back to the problem...

Currently I use a NAS for everything, all documents, photos etc. All the “My xxxx” folders point at the NAS, including “Public xxxx”.
This is copied to a USB HDD every day, in full.

I’ve been moderately bothered for a while about the obvious failure mode, corruption just gets copied to the ‘backup’. The KDE Git story finally made me think that I really ought to do something and I’m after recommendations. I want it to be fire and forget and I guess I’m looking at doing something like keeping full copies longer term but I don’t want to pre-judge.

The NAS is a QNAP 2 bay SOHO device (I think it’s the TS 210 rather than the current TS 212).
It has one 2TB disk (I bought a 2 bay for later expansion).
The USB that’s attached to it is also 2TB.

I am currently accepting of the risk that both disks are in the same house and that I don’t have one offsite (fire, meteor strike etc.). I am not enamoured by the idea of sending 1TB of data up an ADSL line.

My first thought was:
1) Add the second disk and put it into mirror mode as an alternative to nightly copies (loss of expansion capacity but that’s acceptable)
2) Have nightly copies that are over-written seven days later on an external disk - i.e. I can reverse anything in the last 7 days
3) Keep one nightly copy (Sunday for talks sake) from each week for 4 or 5 weeks at which point the oldest one gets written – i.e. I can revert to any given Sunday in the last 4 or 5
4) Keep one copy per 4 / 5 weeks for 6 months

Sounds great until you realise what that adds up to in volume, without compression it turns 1 byte into 16!!
Assume I have 1TB and it doesn’t compress well (videos and photos).
Option 2 requires 7 TB
Option 3 adds a further 4 TB (5 week cycle)
Option 4 adds a further 5 TB

So then I think, versioning, searching t’internet for QNAP versioning brings up lots of links for the offsite storage capability of the device, Amazon S3 and Elephant, not what I need.

And that’s were you, kind people who read this far, come in, so I’ll shut up now Smile | :)

Thanks,
M
