Here are my thoughts on home backup...
- Hard drive reliability should not be a part of your backup strategy. Any hard drive can and will fail (or get lost, stolen, damaged, erased etc.). SSDs are not any more "reliable" than mechanical drives.
- Store two or more copies of your backups. When possible, use different physical media (e.g. a hard drive plus an optical disk, or a hard drive plus a cloud backup service).
- Store your backup copies in different physical locations. One copy at home and one copy at work would be a good starting point.
- Keep your backups up-to-date. Backup new and modified files as often as practically possible. If your computer is struck by lightning right now
- how many of your documents will you lose?
- Check the integrity of your files. A backup will not help you if it contains a copy of the same corrupt file. FastSum
is a nice little utility for calculating and verifying MD5 hash of multiple files.
