Crashplan also only backs up file differences and even if you move
files, they don't have to be backed up again. Crashplan has a free
version that backs up daily, and a Plus version where you can set the
frequency.
You can use the same volume to backup as time machine, and put your
powermail files into the don't backup preference for time machine. thus
for no additional cost, you can get the benefits of time machine for
most files, and use crashplan for Powermail.
Crashplan also has options for off site backup. If you value your data,
you should have more than one backup, and having it offsite is a
excellent choice.
Another free solution (if your files are under 2gb) is dropbox. Pay for
up to 50gb of storage, and sync the data to other machines too. Dropbox
isn't sold as a backup solution, but it does a good job of it. Dropbox
also does data compression, and incremental backups. I'm not sure if it
gives good results for open files...but if you close powermail, it will
backup automatically. I do know some products "support" dropbox, I
assume they insure compatibility when files are open, although I don't
know for sure.
I use Time Machine, Dropbox, Crashplan and Tri-Backup for backup on my
personal machines. I use each product for the specific benefits they
each provide. Time Machine is great, but it's very dumb about big files,
moved files and securing your private data.
I'd never let my backup technology dictate what other products I use.
I am very serious about backup on my personal as well as company
machines. At home, my children and wife have their machines
automatically backed up to my main machine via the free version of
crashplan. One daughter's notebook is backed up to my home machine even
when she is living in the dorms at college.
Although I'm a big fan of Crashplan, there are other products that will
provide excellent backup solutions for big files such as the powermail
database.
