....Note: Always remember to do incremental backups no matter who you are !

You really should get a clue about the topic at hand before you go mouthing off about what other people should do. Right now, you just sound like a complete and utter tool.

 
But this time he makes a good point (amongst the other stuff).

No he doesn't. Incremental backups are notoriously unreliable as a general rule, and rarely ever work for database backups.

Full system backups or, even better, continuous sector-based shadow copy of the volumes are much more robust, reliable backup technologies when used in conjunction with the appropriate database agents.

None of that would have helped anyway in this case unless it was combined with off-site storage of those backups as there's very little backups can help with when a power outage takes out the storage arrays where those backups are stored and prevents them from being usable.

Hence my comment he should get a clue before telling anyone how to run their backups.

I don't think the term "incremental backup" was the right term to use, but the spirit of what s/he was saying is backups could have avoided this mess.

I think they had database backups, problem is they were on the same storage array which was the biggest blunder I think.

So now we're haggling over the size of the increment, are we ?

I do happen to understand the term 'incremental', and was posting on the basis that the rest of us did too, including Chuck.

I was also posting on the basis that there DID need to exist a primary complete backup to which to apply the increments, and that we all knew that too.

YOUR point (Gimli) though is important to me, as in principle I also prefer full backups, as they are easier to safely and successfully administrate.

But given the circumstances that it looked as though there was NO full 'off-primary-media' backup, ANYTHING further might have proven to be better than what we seem to have so far.

I figured as much... my PCs get backed up to my NAS, and my Data is stored on separate drives than the OS on each individual PC...

Which solves two issues; if the OS fails, then I can re-install the OS while keeping the data, and if the whole thing were to melt down then I'd have the Data on my NAS.

It's the best low-maintenance homebrew solution I can think of.

Yes, and if true, also an expensive one, on many levels.

I'm curious however, just how long that a FULL backup of a site and database of DSLR's pre-apocalypsoh size would take to do ?

And as such, how frequently it would be practical to perform one with the site up and running 24-7 ?
