NOTE:
If you are mounting a BTRFS volume from a compatible operating system (see the "Rapid
Recovery release 6.1 operating system installation and compatibility matrix" topic in the Dell Data
Protection | Rapid Recovery Installation and Upgrade Guide), then you must include the following
parameter:
mount -o nodatasum,device=/dev/xxx /dev/xxx /mnt/yyy
9. To verify that the mount was successful, enter the following command, which should list the attached
remote volume:

Unmounting a recovery point on a Linux machine
Complete the steps in this procedure to unmount a recovery point on a Linux machine.
1. Run the Rapid Recovery local_mount utility as root, or as the super user, for example:
sudo local_mount
2. At the Rapid Recovery mount prompt, enter the following command to list the protected machines.
lm
3. When prompted, enter the IP address or hostname of your Rapid Recovery Core server.
4. Enter the logon credentials (user name and password) for the Core server.
A list of the machines that are protected by the Rapid Recovery server displays.
5. Enter the following command to list the recovery points that are available for a specified machine:
lr <line_number_of_machine>
NOTE:
Note that you can also enter the machine ID number in this command instead of the line item
number.
A list of the base and incremental recovery points for the machine will display and includes. The list
includes the line item number, date and timestamp, location of volume, size of recovery point, and an ID
number for the volume that includes a sequence number at the end, which identifies the recovery point.
For example: 7d658e5f-fa08-4600-95f0-5f486bc1b6a4#de0896fd-571a-4cc5-
aeed-264d2c3c72f4#f377e145-dd4d-3ac3-5b15-37ce8f4913ba:2
6. Run the
l or list
command to obtain a list of mounted Network Block Device (NBD)-devices. If you
mount any recovery point, you will get a path to NBD-device after executing the
l or list
command.
7. Enter the following command to unmount a recovery point.
unmount <path_of_nbd-device>
8. Run the
l or list
command to verify that the unmount of the recovery point was successful.

Forcing a snapshot
Forcing a snapshot lets you force a data transfer for the current protected machine. When you force a snapshot,
the transfer starts immediately or is added to the queue if other jobs are running.
You can choose from two types of snapshots.
If you select an incremental snapshot and there is no previous recovery point, a base image is captured. Forcing
a snapshot does not change the timing for any schedules snapshots.
NOTE:
Rapid Recovery supports Window 8, Windows 8.1, Windows Server 2012, and Windows Server
2012 R2 for both base and incremental transfers.
•
A base image is a snapshot of all data on the selected volumes of the machine.
