My TimeCapsule's file system got damaged and I lost my TimeMachine backups. It it possible to backup to two different volumes, for redundancy?

Yes, when you go to the Time Machine preferences, just select Use Both when adding the additional drive.

From: OS X El Capitan: Use multiple backup disks

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 shouldn’t be backed up, the list of excluded items applies to all backup disks.

If you use multiple backup disks, when you click the Time Machine icon in the menu bar and choose Enter Time Machine, you see the timeline for all the accessible disks used for backing up. To see the timeline for a specific disk, click the Time Machine icon, press the Option key, then choose Browse Other Backup Disks.

Note that there is a similar page for each of the last few major OS X releases too.

  • When doing this, does it then backup to both each time that Time Machine runs? – user3439894 May 17 '16 at 21:55
  • @user3439894, from mcelhearn.com/… it shows that it alternates between each drive. – Brick May 17 '16 at 22:03
