The archive bit is a file attribute used by operating systems to determine whether a file has changed since the last time it was backed up. When a file is modified, the archive bit is set to indicate that the file needs to be backed up. Backup software can use the archive bit to determine which files need to be included in a backup.

Different types of backups handle the archive bit in different ways. Here's how each type of backup typically works:

  1. Full Backup: A full backup is a complete backup of all selected files and directories. When a full backup is performed, the archive bit is reset for all files that are backed up, indicating that they have been successfully backed up.

  2. Incremental Backup: An incremental backup only backs up files that have changed since the last backup, regardless of whether they have been backed up before or not. When an incremental backup is performed, the archive bit is set for all files that are backed up, indicating that they need to be backed up again the next time an incremental backup is performed.

  3. Differential Backup: A differential backup backs up all files that have changed since the last full backup. When a differential backup is performed, the archive bit is not reset for the files that are backed up. This means that the next time a differential backup is performed, it will include all files that have changed since the last full backup or the last differential backup.

  4. Copy Backup: A copy backup is a backup of selected files and directories that does not affect the archive bit. When a copy backup is performed, the archive bit remains unchanged for all files that are backed up.

  5. Compressed Backup: A compressed backup is a backup that is stored in a compressed format to save disk space. When a compressed backup is performed, the archive bit is reset for all files that are backed up, indicating that they have been successfully backed up.

Based on the above descriptions, the backup types that will reset the archive bit are:

A. Full Backup: As explained above, a full backup resets the archive bit for all files that are backed up.

E. Incremental Backup: An incremental backup sets the archive bit for all files that are backed up, indicating that they need to be backed up again the next time an incremental backup is performed.

Therefore, the correct answers are A and E.
