On a Mac (iBook), how do we

1) defragment the main harddrive?
2) make a backup of the entire harddrive or certain folders? Would like to burn the backup.
3) optimize?
4) Any other procedure you guys take on a monthly basis?

1. Usually don't need to on a Mac.
2. Not sure, I'm terrible at backups 🙁
3 and 4. Periodically repair permissions in Disk Utility. Also, periodically run "sudo periodic daily weekly monthly" in the Terminal.

If you have .mac, you can use Backup. Otherwise, try Carbon Copy Cloner, which is free!

HFS+ (at least in 10.3, maybe in earlier versions of Mac OS) is kind of self-defragmenting. Whenever a file is opened a set of conditions are checked which are something like is the file fragmented and less than 20Mb and not a heap file. If these conditions are true then the file is moved to a new location on the disk that will result in it being defragmented. So you don't need to defrag.
