Mac / PC / External Drive Backups I know this topic has been covered, however as is typical of the all mighty Internet there appears to be conflicting information so I thought I would try once more. What I am working with: PC with windows XP Mac Air Seagate Free Agent External Hard Drive (NTFS format 1TB) What I want to do: Have my PC regularly backup to the Seagate on the same partition as the MAC. Have my Mac Air reg regularly backup to the Seagate on the same partition as the PC. Have my Mac & Seagate backup to a remote cloud service. Concerns: I have read that some Macs cannot read a NTFS formatted hard drive. I have no issue with that, my Mac accesses it just fine. I have read that having a Mac regularly access a NTFS formatted hard drive can eventually corrupt the NTFS hard drive. Is there truth to this, has anyone experienced it? My current status: Using the software that came with my free agent I have no issues having my PC backing up to the Seagate, it works perfectly. Unless I do it manually (meaning drag and drop), I cannot get my Mac to automatically backup to the Seagate. I searched for free agent software for the Mac however I had no luck. I tried to use Time Machine on the Mac however it wants to reformat the Seagate hard drive to a HFS+ Journaled Format. I read that once I format the Seagate to the HFS+ Journaled Format that my PC will not be able to access the drive. Is this true? Does anyone have any suggestions or has anyone accomplished what I am trying to do? If so can you suggest software for the Mac and software for the PC that will run scheduled backups. Also does anyone have any suggestions on a reasonably priced and secure cloud / offsite storage service for a regular backups of about 1 TB of data? Thanks and let me know if you need any more information.
