I run a small home network with a mostly Windows computers but now with my new Mac included. Right now I am backing each of the computers up separately. I am looking into a networking backup hard drive such as a Seagate Black Armor or WD World Edition. My question is whether I can backup all the computers on the network or if the Mac will not be backed up because of the different hard drive formats on the computers. If I format the network backup drive using NTFS, will it be able to backup and restore to the Mac as necessary. Will the Mac be able to read/write to the network backup drive as necessary? Any other backup suggestions for this mixed environment would be appreciated. Thanks!
