Multiple drives

[mribri999]

More of a comment than issue... First, Thank you! - I have wanted this solution forever!

I use TM, happy with backups every 1-2 days, but prefer 2 physical locations: home and work. So I modified the easy-backup-and-eject.sh script manually to add a check/backup/eject for 2 different drives.

One option to keep the simple "replace" strategy of the install would be to just have the install allow an extra optional drive.

Slight addendum: TM remembers the last drive, and changing the drive requires root access to terminal, which may or may not be preferred. The --rotation option works around this by using TM's "algorithm." So essentially the script after modifying is:

#!/bin/sh
drivea='home-drive'
driveb='work-drive'
date
if mount | grep "$drivea" ; then
        echo "Volume '$drivea' mounted, starting backup..."
        sudo tmutil setdestination "/Volumes/$drivea"
        tmutil startbackup -b --rotation
        diskutil unmount "$drivea"
else
        echo "Volume '$drivea' not mounted, skipping backup."
fi

if mount | grep "$driveb" ; then
        echo "Volume '$driveb' mounted, starting backup..."
        tmutil startbackup -b --rotation 
        diskutil unmount "$driveb"
else
        echo "Volume '$driveb' not mounted, skipping backup."
fi

Hope this helps!
