I have a MacBook Pro I'd like to backup using Time Machine. I have money to purchase any storage solution that will allow me to keep 4TB+ of "history" of a FileVault volume. My current solution gives me 2 TB which is not enough in terms of being able to "travel back in time" far enough. What to buy?
- Does Time Machine support NAS? (USB 2.0 seems like a bottleneck, my NIC is 1Gb)
- A FireWire 800 external disk > 2 TB?
- An external RAID?
4TB+ is really a requirement and backing up to tape is not viable as I need a fast restore.
Can Time Machine "aggregate" external drives to allow for "longer time travel"? I have another computer I could use to run software RAID on it (USB though, not FC/SAS/SCSI/FW) but to me this would be too risky... would it not?
How about migrating older Time Machine backups to slower/cheaper/larger/more power efficient drives? Would the interface stay the same?
