General properties for backup-to-disk folders

General properties for backup-to-disk folders provide information about the folders.

See Creating a backup-to-disk folder by setting properties.

Table: General properties for backup-to-disk folders

Item

Description

Name

Displays the name of the backup-to-disk folder. Backup-to-disk folder names must not exceed 128 characters.

See Renaming storage devices.

Path

Displays the path where the backup-to-disk folder is to reside. For a removable backup-to-disk folder, the drive on which the folder is located appears.

The backup-to-disk path name, which includes the backup-to-disk folder name, must not exceed 512 characters.

A browse button next to the Path field lets you browse to other paths.

See Changing the path of a backup-to-disk folder.

Pause

Indicates if the backup-to-disk folder is paused.

Enable

Indicates if Backup Exec has exclusive use of this backup-to-disk folder. If the check box is clear, the device is disabled and cannot be used by Backup Exec. The device is available for other applications.

Online

Indicates that the backup-to-disk folder is online if a dimmed check box with a check mark appears. If the folder is offline, a check mark does not appear. No operations are allowed on the folder until it is online again.

The folder appears as offline if the following occurs:

  • The backup-to-disk folder is on a remote computer and connectivity is not available.

  • The access rights to the folder or to the remote computer are incorrect.

  • The backup-to-disk folder is write-protected.

See Changing the status of a device to online.

Maximum size for backup-to-disk files

Displays the maximum size for each backup-to-disk file contained in this folder. The file size can be from 1 MB to 4096 GB. The default is 4 GB.

Backup-to-disk folders that were created with earlier versions of Backup Exec continue to use the default file size of 1 GB.

If you create smaller but more numerous backup-to-disk files, performance may be slower. If large backup-to-disk files are created, file system limitations could cause memory allocation problems or network issues, especially if the backup-to-disk files are stored across a network.

This option works with the option Maximum number of backup sets per backup-to-disk file.

Allocate the maximum size for backup-to-disk files

Creates the backup-to-disk file at the maximum size to reduce disk fragmentation.

You may want to increase the append period. However, increased append periods can cause an increase in the overall overwrite protection period since the overwrite protection period starts at the end of the last append job. This can result in fewer backup jobs being targeted to this backup-to-disk folder. To avoid this, set the maximum size for backup-to-disk files to an appropriate size.

When the backup-to-disk file is initially created at the maximum size, the backup job may be delayed while Backup Exec creates the file. The backup job remains in a running state until the backup-to-disk file is created and data can be written to it.

When you select this option, Backup Exec hides the option Maximum number of backup sets per backup-to-disk file. As a result, all of the space that is allocated to the backup-to-disk file is used.

This option is not available for a removable backup-to-disk folder.

Maximum number of backup sets per backup-to-disk file

Displays the maximum number of backup sets to be written to each backup-to-disk file in this folder. The maximum number can range from 1 to 8192. The default is 100.

Fewer backup sets in a backup-to-disk file may allow the overwrite protection period to expire sooner, and disk space to be reclaimed faster.

Allow x concurrent jobs for this backup-to-disk folder

Displays the number of concurrent operations that you want to allow to this folder. This number can range from 1 to 16.

This option is not available for a removable backup-to-disk folder.
