Thanks for all the links davidanders,
I like that Silverkeeper uses mac's I/O so you don't need software to access the backup. If my hdd dies and silverkeeper's download link disappears and I can't find the dvd w/ my downloaded apps backedup I'm still ok. I wish my mac could use RAM discs. I still need something that will burn backups to dvd. Without nero's multisession compilations I need something that will keep track of which files changed in what folders since the last backup.
I'm probably going to try out Superduper. It's reasonably priced [cheap] and I keep reading positive opinions about it. I still need to read over my Time Machine notes.
Chronosync info had a link to a good article on partitioning for mac. Here
. First thing I need to do is partition my ext hdd, but first I have to figure out partition number and sizes and that depends on my backup strategy and the programs I decide to use.
The backup strategy link clued me in on getting some verbatim gold dvd's. I mostly use regular verbatim's that have held up well, but I should have one set on archival quality dvd in my security box at the bank.
