Backup Advice

[mattyHM]

I currently run a G4 Powerbook and have an external 250Gb HD split into partitions. I have backed up my previous system (10.3.9) successfully using the back up all files option to one of the partitions on the external HD. I have now upgraded my OPsys to 10.4.8 but wish to keep the old back up archived and make a new backup of the latest Opsys Mac OS X 10.4.8 (hopefully to the same external HD partition), as this partition that holds the copy of my 10.3.9 OpSys still has 45 GB of free space.

So in a nutshell, is there any way I can back up this current system which will take no more than 15GB space to the same partition without erasing the previous backup.

You indicate it's split into partitions -- do you have a partition to store it on? You can't *really* store it on the same partition except in an image, and I think that would be a mistake.

Hello

The 250 GB HD is split into 4 Partitions, 2 are 50 Gb in size and 2 are 60 GB, as the system that I'm backing up is less than 15GB. I have allocated one 50GB partition to use as the back up (there is data on the other 3) so this leaves quite a bit of space free.

So would the best option be to re-partition this 50GB (with 35Gb free after the 10.3.9 backup) into two 25GB bootable partitions one 10.3.9 and the newer 10.4.8.

It's really a question about how to utilise the space on the HD effectively.

Yep -- I think that would make the most sense.
