Dell EMC Data Domain

Create a new Backup Destination (Dell EMC Data Domain)

Go into the backup destination menu and click on Create a backup destination.
Provide a name and description for the new backup destination.
Specify the retention days for full and incremental backups.
Specify the retention versions for full and incremental backups.
Choose and assign the node configuration to which you want to attach the new backup destination.
Add to one or more storage paths.
- example - /vprotect_data/backupdestination
Save the configuration.

DD Boost FS Plugin

To boost the backup process we recommend using a single Storage Unit and mtree, and subfolders on the BoostFS for multiple backup destinations (with possibly different retention settings).
- No additional data copy is needed in the store phase if staging is using the same file system as the backup destination.
- The Setup assumes a single Storage Unit and a single mtree for all backup destinations.
- The staging space should always be a top directory, and all backup destinations should be defined as separate subfolders of this file system.
- Storware Backup & Recovery handles retention, and each backup destination may have different retention configured.
- A single Storage Unit will also affect replication as it has to cover all backup destinations, and may replicate temporary data from the staging space or mounted backups.
Sharing the same BoostFS across multiple nodes allows the administrator to create backups on one node (one host/environment) and restore using a different node (to a different host/environment).
- UID/GID ownership and permissions must allow Storware Backup & Recovery to read/write contents of the BoostFS share.
- To meet these requirements, the user and group named vprotect that was created during the installation process must have the same UID and GID on each Storware Backup & Recovery node machine. You can create this before installing Storware Backup & Recovery packages or change it after installation.
Data Domain User requirements:
- user must have backup-operator management role
- user must be assigned to DD Boost Storage Unit

Prepare your PowerProtect DD as a backup destination:

Download BoostFS RPM from the Dell EMC site.

Install BoostFS:

rpm -ivh DDBoostFS-7.0.0.0-633922.rhel.x86_64.rpm

Save the password for BoostFS.

# Syntax
/opt/emc/boostfs/bin/boostfs lockbox set -d [DataDomain_IP_OR_DNS_NAME] -u [Access_User_Name] -s [Storage_Area_Name]
# Example
/opt/emc/boostfs/bin/boostfs lockbox set -d 10.1.10.100 -u vprotect -s vprotectbackup

Add the /etc/fstab entry:

# Syntax
[DataDomain_IP_OR_DNS_NAME]:/[Storage_Area_Name] /[Mount_Point] boostfs defaults,_netdev,bfsopt(allow-others=true) 0 0
# Example
10.1.10.100:/vprotectbackup /vprotect_data boostfs defaults,_netdev,bfsopt(allow-others=true) 0 0

Mount the fstab entry:
```
mount -a
```

For a manual, one-time mount you can run this command:

# Syntax
/opt/emc/boostfs/bin/boostfs mount -o allow-others=true -d [DataDomain_IP_OR_DNS_NAME] -s [Storage_Area_Name] /[Mount_Point]
# Example
/opt/emc/boostfs/bin/boostfs mount -o allow-others=true -d 10.1.10.100 -s vprotectbackup /vprotect_data

Confirm with df -h that your /vprotect_data is mounted Note: Remember to specify the backup destination path as a subdirectory of /vprotect_data if you would like to use the same storage unit as a staging space and backup destination - for example: /vprotect_data/my-backups.
```
mkdir /vprotect_data/my-backups
```
Set ownership to the vprotect user on the directory /vprotect_data.
```
chown vprotect -R /vprotect_data
```
Set ownership to the vprotect user and data domain group on the directory /vprotect_data/my-backups.
```
chown vprotect:gid /vprotect_data/my-backups
```

where 'gid' is the GID of data domain user specified in Synthetic DD Boost backup destination configuration.

Set read and write privileges for both user and group to the directory /vprotect_data/my-backups.
```
chmod 0775 /vprotect_data/my-backups
```

Note: Synthetic DD Boost

To configure a synthetic backup destination, follow the instructions that are described in the documentation.

Microsoft Hyper-V

Additional actions are required when protecting Microsoft Hyper-V. Mounting the Data Domain share should be done in the same way as described above. After mounting the share, do the following:

sysadmin@localhost# user show list

User list from node "localhost".
Name        Uid   Role              Last Login From   Last Login Time            Status    Disable Date
---------   ---   ---------------   ---------------   ------------------------   -------   ------------                   enabled   never
vprotect   501   admin             <unknown>         never                      enabled   never
--

Log in to Storware Backup & Recovery Node and set the vprotect user ID to the same as the DataDomain user. If there are multiple nodes, the ID must be changed on each of them.
- First, make sure that no other user has this ID
  grep ":YOUR_UID:" /etc/passwd
- If the command returns a result, it means that this UID is taken, for example:
  [root@localhost ~]# grep ":501:" /etc/passwd user:x:0:0:user:/user:/bin/bash
- In this case, the ID of that user should be changed to another first, and only then ID of the vprotect user can be changed.
  If this command returns no results, it means that this ID is not taken and it is possible to change the vprotect user ID
  # Stop vprotect services systemctl stop vprotect-server vprotect-node # Change vprotect user and group ID usermod -u 501 vprotect groupmod -g 501 vprotect

Reload permissions

chown vprotect:vprotect -R /opt/vprotect/
chown vprotect:vprotect -R /tmp
chown vprotect:vprotect -R /mnt/vprotect/
chown vprotect:vprotect -R /vprotect_data/
# If you use a path other than /vprotect_data for staging space / backup destination, change the permissions for it as well.
# Start vprotect services
systemctl start vprotect-server vprotect-node
