Backing up and Restoring the Node User Database Records

Follow these instructions to back up and restore your node user data up to the time of the backup operation. To backup the entire database, see Backing up and Restoring a Node Database.

Back up the node user data from the Redis database by running the following command:
```
# sudo /opt/aspera/bin/asnodeadmin -b /filepath/database.backup
```
Important: When backing up the Redis database, all user data up to that point in time will be saved to the backup file. Restoring the database (see Step 2, below) does not delete users added after this snapshot was taken. Thus, if you added any users after backing up the database, they will still exist in the system and will not be affected by the restore operation.
Restore the node user data to the Redis database by running the following command:
```
# sudo /opt/aspera/bin/asnodeadmin -r /filepath/database.backup
```
Note: If you do not want to keep users that have been added since the last backup operation, delete them after performing the restore with the following command:
```
# sudo /opt/aspera/bin/asnodeadmin -du username
```
Restart the asperanoded service using the following command.
Run the following commands to restart asperanoded:
```
# systemctl restart asperanoded
```
or for Linux systems that use init.d:
```
# service asperanoded restart
```
