Abstract
Official abstract text for this publication.
Directory attributes are provided so that the time for creating an incremental backup of a file system by a scan of the file system tree is proportional generally to the number of files that change between backups instead of the number of files in the file system. A tree modification attribute indicates whether or not any file in a directory tree has changed since the last backup. If no file has changed in the directory tree, then the entire tree is skipped during the scan for changed files. In addition, a list is compiled of the files in the directory that represent branches having at least one changed file, so that the list is scanned instead of the directory entries. When a file is changed for the first time since the last backup, the file is queued so that the directory attributes are updated in a background process.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for use in rapid incremental backup of changed files in a file system, the method comprising: scanning a file system hierarchy of a file system in a top-down manner for determining a list of changed files for performing incremental backup of the file system; evaluating a directory tree modification attribute of each directory hierarchy of the file system hierarchy of the file system in the top-down manner, wherein the file system hierarchy include…
