Requirements for creating a removable backup-to-disk folder

A removable backup-to-disk folder works as follows:

Supports spanning of backup sets from one piece of media to another.
Does not support concurrent operations.

You should not share removable backup-to-disk folders between media servers.

You can create removable backup-to-disk folders on any device that has removable media, provided the device appears as a drive letter and is formatted with a file system.

Devices with removable media can include the following:

CDR-RW
DVD-RW
ZIP
REV
Removable hard disk

Note:

For CDR-RW and DVD-RW, third-party software must be used to format the media before it can be used with Backup Exec.
