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. +-----------------------------------------------------------+ Bill Schjelderup, President [email protected] COMPanion Corporation 801-365-0555 voice 1831 Fort Union Blvd. 801-943-7752 fax Salt Lake City, Utah 84121-3041 www.companioncorp.com +-----------------------------------------------------------+ Nusquam est qui ubique est. - He who is everywhere is nowhere.
