System Restore and Backup follow-on question
Reader Cliff solved a backup problem using the information in the April 25 item, “When to reduce System Restore’s disk space,” but he then had a follow-on question.
- “I was having trouble with Windows Backup under Windows 7. I was getting a shadow copy error.
“Thanks to your column in this week’s Windows Secrets concerning space allocation for backup and restore, I changed my allocation from one percent to 12 percent and then successfully backed up my hard drive with Windows Backup.
“But I have a question about the backup. When I let Windows choose what to back up, it backed up my user data and then did a system image backup. I know that when I do backups in the future it will back up only new files and those that have changed. If I want to restore a modified file, does it show only the latest file or does it keep several copies of that file?”
Glad the article helped, Cliff!
Indeed, your backups will fail if the size of your backup exceeds whatever space you’ve allocated. The same thing can happen when a disk gets too full — if there’s not enough space to store the backup, the backup fails.
