This knowledge base article addresses the challenge of successfully mounting and unmounting image backups on the Linux backup server using the VembuVirtualDrive.

Once the backup is completed successfully without any issues, you can mount the backup on the backup server side to access image files (VHD, VHDx, VMDK & IMG) from VembuVirtualDrive.

1. Navigate to the Vembu BDR console:

Top menu Management > Click Server Management > Manage Virtual Drive.

2. View the list of available backups for virtual drive mount/unmount.

1. Click the "Mount" button for the specific backup you want to mount.
2. Confirm the action by clicking "Yes."
   

3. To mount image files on the VembuVirtualDrive, ensure the fuse package is installed. If not, follow these steps to install:

1. To install Fuse package: `apt-get install fuseiso`
2. Configure fuse and start in service mode:
   

sudo modprobe fuse

sudo adduser vembu fuse

4. Once Fuse is installed, follow these steps to mount .img files available on the BDRSuiteVirtualDrive:

1. Predict the image as a file system:
   

losetup /dev/loop7 ./drive.img

1. Create the mount point:
   

mkdir /mnt/lp4

1.  Find the offset information:
   

fdisk -l drive.img

1. Multiply the offset value with the sector by 512.
   
2. Mount the image:
   

mount -o loop,offset=(512*offset value)/dev/loop4 /mnt/lp4

Example: `mount -o loop,offset=32256 /dev/loop4 /mnt/lp4`

1. The new disk will be mounted, allowing access to specific files or folders for copying.
   

5. Once the recovery process is completed, unmount the backup:

1. Navigate to VembuBDR console:
2. Top menu Management > Click Server Management > Manage Virtual Drive.
3. Click the "Unmount" button to proceed with further backups.
