What is an archive bit?
A file's archive bit is a marker that indicates whether the file has been modified. An archive bit that is set (turned on) indicates that the file has changed since it was last backed up or copied.
Why turn off a file's archive bit?
Turning off (resetting) the file's archive bit is a procedure that affects what Arcserve Backup will back up or copy the next time. An archive bit that is off indicates to Arcserve Backup that this file has not changed since it was last backed up.
The method you select determines whether Arcserve Backup will back up or copy all files, or only files whose archive bit is on. It also determines whether Arcserve Backup will turn off the archive bit after the file has been backed up or copied.
Note: A file's archive bit can also be turned on and off by other applications.
Important! The Arcserve Backup Copy feature can set or clear file archive bits that may affect your Incremental or Differential backups. Plan your copy operations carefully to ensure that they do not interfere with your backup jobs.
