摘要: Methods and systems for backing up and restoring the state of a computer system are disclosed. Computer resource use is minimized by combining the backup methods of file copying and file logging. During backup, copies are stored of those files that are expected to change frequently. For other files, changes are noted in a change log and backup copies may be made if they would be useful when later restoring the files. Restoration proceeds by overwriting the frequently-changing files with stored copies and by undoing the changes to the logged files.
