Backup method for files

Select one of the following backup methods:

  • Full - Back up files

    - Using archive bit (reset archive bit). Includes all of the files selected for backup and resets the archive bit to indicate that the files have been backed up.

    - Using modified time. Includes all of the files selected for backup and allows the use of incrementals and differentials using the modified date and time stamp.

    -Copy the files. Includes all selected data but does not reset the archive bit. It does not affect your backup strategy or media rotation scheme.

    - Archive the files (delete files after successful copy). Backs up the selected data, verifies the media, and then deletes the data from the volume. For data to be deleted, rights to delete a file must be granted; otherwise data is backed up, but not deleted.

    Backup Exec does not delete data from Backup Exec Agent workstations when using the archive feature.

  • Differential - Back up changed files since last full

    - Using archive bit (does not reset archive bit). Includes all files that changed (based on the archive bit) since the last full backup. It does not affect your backup strategy or media rotation scheme because the archive bit is not reset.

    - Using modified time. Includes all files changed since the last full backup, using the files' last modified date and time stamp. Make sure that the same script or selection list is used for the differential backup that was used for the full backup.

  • Incremental - Back up changed files since last full or incremental

    - Using archive bit (reset archive bit). Includes only the files that have changed (based on the archive bit) since the last full or incremental backup and resets the archive bit to indicate that the files have been backed up.

    - Using modified time. Includes all files that have changed since the last full or incremental backup, using the files' last modified date and time stamp. Make sure that the same script or selection list is used for the incremental backup that was used for the full backup.

  • Working Set - Back up files

    - Changed today. Backs up all files that were created or modified today.

    - Last accessed in (x) days. If you select this backup method, you can then indicate in the Files accessed in x days field that you want to include data that has been accessed in a specific number of days.

    See Understanding backup methods and their advantages.

Files accessed in x days

If you selected Last accessed in (x) days in the Backup method for files field, use this field to specify the number of days for which to include accessed files.

Symantec recommends that you specify at least 30 days in order to include the data needed to make your system operational if you have to restore a working set backup.

Use the Microsoft Change Journal if available

Select this option if you want to use the Microsoft Change Journal to determine which files have been modified since the last full backup. This option can only be used with NTFS volumes.

This option is available when you select one of the following backup methods:

  • Full - Back Up Files - Using modified time. This method is not available when performing offhost backup.

  • Differential - Back up changed files since last full - Using modified time

  • Incremental - Back up changed files since last full or incremental - Using modified time.

In addition, this option becomes available if you select the Collect additional information for synthetic backup and for true image restore check box.

If you use the Change Journal with the option to collect additional information for synthetic backup and for true image restores, the archive bit is not reset, even if you selected a backup method that has "reset archive bit" in the name.

If you are backing up volumes with junction points that were created by linkd.exe, you should not use the Microsoft Change Journal. Junction points are not followed properly in this situation.

Preserve tree on archive

Select this option to retain the directory structure on the hard drive of the files backed up in an archive job. This option is only available when Archive is selected as the backup method.

Collect additional information for synthetic backup and for true image restore

This option displays only for templates. It is used with synthetic backup jobs and true image restore jobs. It specifies that Backup Exec collects the information required to detect files and directories that have been moved, renamed, or newly installed since the last backup, and then includes those files and directories in the backup jobs. If this option is not selected, Backup Exec skips these files and directories if their archive bits are unchanged. With this option selected, Backup Exec compares path names, file names, modified times, and other attributes with those from the previous full and incremental backups. If any of these attributes are new or changed, then the file or directory is backed up.

Backups that have this option selected require more disk space, and take more time to run, than backups that do not.

You must select this option for the baseline and incremental backup template in a synthetic backup policy.

See About the synthetic backup feature.

Verify after backup completes

Select this option to have Backup Exec automatically perform a verify operation to make sure the media can be read once the backup has been completed. Verifying all backups is recommended.

Compression type

Select one of the following:

  • None. Select this option to copy the data to the media in its original form (uncompressed). Using some form of data compression can help expedite backups and preserve storage media space.

    Hardware data compression should not be used in environments where devices that support hardware compression are used interchangeably with devices that do not have that functionality.

    For example, if a drive that does not support hardware compression is added to a cascaded drive pool that includes drives supporting the feature, hardware compression is automatically disabled. You can manually re-enable hardware compression on the drives that support it, but this results in media inconsistency. If the drive that supports hardware compression fails, the compressed media cannot be restored with the non-compression drive.

  • Software. Select this option to use STAC software data compression, which compresses the data before it is sent to the storage device.

  • Hardware [if available, otherwise none]. Select this option to use hardware data compression (if the storage device supports it). If the drive does not feature data compression the data is backed up uncompressed.

  • Hardware [if available, otherwise software]. Select this option to use hardware data compression (if the storage device supports it). If the drive does not feature hardware data compression, STAC software compression is used.
