Problem

What is the difference between a B2D (Backup-To-Disk) and RB2D (Removable Backup-To-Disk) folder?

Solution

There are two types of Backup-To-Disk (B2D) folders in Backup Exec 10.x and later, B2D folders and removable B2D folders.  Below is a break down of the differences between the two.  

B2D folders:

Create a backup-to-disk folder in any location where a file can be written, such as:
  • NTFS partitions (local or remote)
  • Network Attached Storage (NAS) devices
  • DFS shares
  • FAT/FAT32 partitions (local or remote)
  • RAID drives with any configuration
  • NFS volumes

Note: This type of folder supports concurrent operations from one or more media servers. When creating this type of folder, we can specify both device or the path for the folder as well.
 
Removable B2D folders:

Create removable backup-to-disk folders on any removable device, provided the device appears as a drive letter and is formatted with a file system. Removable devices can include:
  • CDR-RW
  • DVD-RW
  • ZIP
  • Jazz
  • Removable hard disk

This type of folder supports spanning of backup sets from one piece of media to another, but does not support concurrent operations. For devices such as  DELL RD1000, HP RDX, & Tandberg RDX are able to span cartridges when used as a removable backup to disk.

Note:  

  • For CDR-RW and DVD-RW, third-party software must be used to format the media with a file system before it can be used with Backup Exec.
  • At this time Backup Exec does not support swapping out hard disk drives with either type of B2D folder. Removable hard disk drives can be removed and reattached at a later time but they cannot be swapped. This type of folder should not be shared between media servers. When creating this type of folder, only the device must be specified, not a path.
