I have a desktop computer running Windows and two Mac laptops. The desktop computer has two internal hard drives, both NTFS and both encrypted with TrueCrypt (yes, I know TrueCrypt is supposedly not safe to use anymore).
Every night, all three machines get backed up to the desktop computer's secondary drive. Once a month, I clone the desktop computer's secondary drive onto an external hard drive that I keep at work, which is also NTFS and encrypted with TrueCrypt. I think this is a pretty good setup because:
- I have 3 copies of my data that is >1 month old
- I have 2 copies of my data that is <1 month old
- All copies of my data are encrypted
The downside I have found with this setup is that the data from the Mac laptops don't always do well with being copied onto an NTFS drive. I think it would be better to have my three machines all get backed up to a drive that uses a file system that plays well with Windows and Mac data. I also want it to be encrypted, though. I'm wondering what the best approach for this is. I have very, very little experience with NAS, so I could be mistaken about this, but isn't it typical for a NAS to try to be smart with your data and hold your hand through the process? I kind of don't want that. I just want my data encrypted and I will create an off-site backup myself like I'm currently doing. Any suggestions? Thank you!
