You can restore files from a backup of a physical Linux server created with or without indexing. To prepare a backup with guest files indexing, take these steps:
- Check for the following utilities to be installed on the Linux server: mlocate, gzip, and tar. These utilities are required for guest indexing; if they are not found, you will be prompted to deploy them to support index creation.
- Enable guest file system indexing using the backup job wizard. For details, see the corresponding section section of the Veeam Agent User Guide.
- Run the backup job with guest file system indexing enabled.
- Make sure the indexing data was imported to Veeam backup database, and catalog data replication completed successfully. For details, see the Performing Catalog Replication and Indexing section.
Whether you will be restoring from a backup with or without guest files indexing, you will need to prepare an VM to operate as an FLR helper appliance.
Preparing FLR Helper Appliance
To perform Linux guest files restore, you should configure an FLR helper appliance on the Veeam backup server with which Veeam Agent is integrated. FLR helper configuration is similar to that described in the “Multi-OS File Level Recovery” section of the Veeam Backup & Replication User Guide. The only difference is that for restore of a physical machine, you can configure a helper appliance to work on a VM running on the platform of your choice (VMware or Hyper-V). Helper appliance settings are saved in Veeam Backup & Replication database on per-user basis; they will be applied each time the certain user starts Linux file-level restore.
When Linux guest file-level restore is started from Veeam Backup Enterprise Manager, FLR helper configuration settings are obtained from the database of the corresponding Veeam backup server. If no FLR helper configuration is found for the current user account, Veeam will use the default settings (those set during the latest FLR appliance configuration process in Veeam backup console). Thus, before starting Linux file-level restore from Enterprise Manager, make sure that Linux FLR helper settings were configured on Veeam backup server.
If you plan to deploy multiple FLR helper appliances in order to restore Linux machines backed up by Veeam Agents integrated with different Veeam backup servers, consider that their initial configuration should be performed on the corresponding Veeam backup servers. Centralized configuration via Enterprise Manager is not supported in the current version.
- Make sure that then DNS name of the target (original) Linux server where you plan to restore the files is resolved properly.
- During guest files restore to the original location, you will be prompted for the credentials to access the target Linux server. Specify user name and password or private key for the account with sufficient access rights.
