Off-site Backup to a NAS Device Using BackupAssist (Synology Example)

BackupAssist Synology WebDAV setup

In case you missed the announcement, BackupAssist recently added WebDAV to the suite of backup job types the software is able to support. Intended for those who wish to back up their data to an off-site destination, the protocol enables admins to create encrypted, incremental backups to either a third party hosting company, another Windows server or a NAS device.

The latter is a popular choice, particularly for the smaller business. They’re a good option because once the hardware’s paid for, there’s no monthly recurring charge as you’d tend to expect from a cloud storage provider. Also, the portability of the small units means they can be ‘seeded’ to locally and then moved. In most cases, you have physical access too, which means you’re not relying on an Internet connection for your data in disaster recovery scenarios

In this post, I focus on the steps for configuring one of the more common NAS devices I come into contact with, the Synology. The requirements will be the same for other brands, however, the exact steps and screenshots will of course differ. Continue reading

Rsync stopped working with Synology NAS update

We have recently encountered a few customers who are seeing BackupAssist Rsync jobs connecting to a Synology NAS failing due to authentication issues that have previously working without issue. This appears to have coincided with a recent Synology NAS firmware update.

The issue appears to be related to the Synology no longer having a password set for the ‘root’ users account.

Since the update, Synology have locked the use of the root user account (in actual fact they have locked it out using a “*” as a password hash).

Here is how to re-enable the root access for ssh access (Rsync over SSH):

1. Login using Putty or any other SSH client with administrator account (usually “admin”)
2. You will be asked for a password. Enter the one for the Synology administrator account you use to access the NAS via the web interface.
3. You should get a command prompt.
4. Enter: sudo su –
5. You will be then asked for a password. Enter again the one for the administrator account.
6. You will get a command prompt root@…
7. Enter command: synouser –setpw root your_new_root_password
8. Rerun the backup job to check its working ( you may need to re-register the connection first in the Destination tab of the job).
