Advantages and Disadvantages of File Backups • Advantages: • Efficient for very small backups (much less than the entire hard drive) • Ease of use (GUI) • Inexpensive (Microsoft Backup) • Disadvantages • Restoring may require a bootable computer • More capable products may be pricey ($50 or more)
My Backup Strategy • Monthly backup • Disk image using PowerQuest Drive Image • Weekly backup • Incremental using Microsoft Backup • Daily backup • Limited incremental using Microsoft Backup
Additional Thoughts on a Backup Strategy • Don’t put it off! • Make sure you can restore backed up data • Keep redundant backups • Two different discs • Two different media types (e.g. hard drive and CD) • Off-site storage • Online backup service • Safe deposit box • Nothing lasts forever • Media could good bad • Media may become obsolete (e.g., 5 ¼” disks)
