OS X Mavericks: Use multiple backup disks

Use multiple backup disks

For extra security and convenience, you can back up to multiple disks. If you work in two locations, you may want to keep backup disks in both places.

Time Machine rotates the backup schedule among the disks. For each disk, Time Machine backs up everything that’s changed since the last time that disk was used. If you designated items that should not be backed up, the list of excluded items applies to all backup disks.

If you use multiple backup disks and you choose Enter Time Machine from the Time Machine menu, you see the timeline from the disk most recently used for backing up. To see the timeline from another disk, press the Option key, then choose Browse Other Backup Disks from the Time Machine menu in the menu bar.
