My system: iMac (Retina 4K, 21.5-inch, Late 2015), 16GB, 1 TB Fusion Drive, High Sierra (moving to Mojave soon)
My backup system:
- 2TB Time Capsule using Time Machine
- 1TB IOmega USB external drive using Time Machine and SuperDuper
- 500GB OneTouch USB external drive using SuperDuper
The Iomega backup drive is full and I’ve ordered a WD 4TB drive recommended by the Wirecutter. The imminent arrival of the drive brings to mind several issues that I’m sure members of this list can help me address.
Is is possible to move the time machine backup file (Backups.backupdb) from the Iomega drive to the new drive so I can preserve the backup history on the new drive? If so, what’s the best way to do it?
I plan to format the WD drive before using it. Because I will be moving to Mojave, and I understand my Fusion Drive will be converted to the new file format (HPFS?), should I format the WD drive using the new file format? If so how can I do that before I install Mojave?
I think I’d rather have SuperDuper backups on separate drives (at least virtually) from the Time Machine files. Is there any reason not to partition the new WD drive into two ‘drives’ to keep things separate? (I realize a physical drive failure would doom both, but I do have the IOmega and OneTouch drives to use for SuperDuper, and the Time Capsule will still have the Time Machine files.)
Thanks for any thoughts!
