Backups are not optional. Some day your disk will crash or your array will fail to start up, and if you have a backup you will only have a bad day or two. If you don’t have a backup the pain and damage will last much longer.
• Backup Safety
◦ Do not put the only copy of data on a flash drive.
◦ Do not keep your only backup in the same location as your computer. • Backup Options
Many MKI users back up to both CrashPlan and Time Machine. The latter can be restored more quickly over USB or other physical interface, but the former protects against theft of both laptop and backup, or physical damage to the backup disk.
For backing up larger volumes of data please contact Ricky Leiserson, who can discuss backup strategies and ways to implement plans (e.g. MIT’s TSM).
