I used to use Retrospect back in the OS9 days and that was a fantastic programme. I still have files going back too many years than I like to mention and all are 100% retrievable.
Nowadays on OSX I don’t use it any more. The programme still works fine but unfortunately if you use single sided DVDs (I can’t use the cased double sided ones anymore no matter what I do to try and get the external drive to recognise them) it tends to hiccup every now and then but that’s nothing to do with Retrospect more the fact that you have to handle the DVDs as if you are in a clean room as the slightest (and I do mean slightest) finger print on the surface will mess everything up for you.
I then moved across to simply using Toast with DVDs and spanning the backup information across disks which works fairly well. Each disk set has its own search programme so that helps some way in finding files after you have backed them up. You can then also use a programme such as CD Finder or one of the other many programmes to catalogue all your disks.
I did just the other week start using Time Machine with a Lacie drive but just a couple of days ago had the drive lock up on me. I could read everything on the drive fine but couldn’t write anything to it. Seems when I ran DiskWarrior over it that there were a lot of overlapped files on the drive, thousands to be precise. Not sure if this was to do with Time Machine or not but it does write an awful lot of files to a disk so it could have been fragmentation because of that. I had to then back everything up from my backup 😉 to DVD and then re-format the drive. Not a fun thing to do with a 500GB drive!! :down:
I have looked at all the other backup strategies at one point or another and Synk does seem to be a nice programme in that it knows every time what to backup and gets on with it straight away much like Time Machine does. Other backup programmes have to scan the hard drive first for file differences which depending on the size of your drive could take anywhere up to 40 minutes or more.
At this time though I think that DVDs are the best bet and safest to back up to as long as you handle them with absolute care when first writing them.
Don’t know if any of that helps at all.
Best wishes,
