Some background info
I've been a happy Sophos user for many years now, always used the software versions ( running on VMWare ESXi ). Unfortunately my raid setup failed me, so I'm in the process of recreating all my VM's including my virtual Firewall. I had set it up to e-mail the configuration on a weekly basis, so I thought it would be a walk in the park.... The last time I had to install Sophos, I started with Firmware: SFOS 17.0.6 MR-6
The annoying error
It keeps telling me: "Backup cannot be restored on current device" no matter what I do... The 'why' would be sooooo helpful so I could perhaps fix it! I briefly tried looking in log files ( /var/tslogs ) but could not find a relevant file and it’s a bit to much to open them all.
Things I already tried:
- I downloaded the latest ISO file from the Sophos website ( SFOS 17.5.8 MR-8 ), installed it no problem, but could not recover the configuration. I noticed I wasn't up to date yet, my latest backup config said it was made by SFOS 17.5.6 MR-6, I searched: That ISO could not be found nor was there any way to downgrade.
- Fortunately I found an old copy of my original installation ISO ( 17.0.6 MR-6 ), installed that, same error. Because I was already a little annoyed I did not payed attention, the checkbox to update to the latest version was checked… But this time I could choose to downgrade, I tried the first and last configuration backups with SFOS 17.0.6 MR-6, same error
- Because I could not rule out something went wrong with the up- or down- grade, I started with another fresh installation of SFOS 17.0.6 MR-6, this time unchecked the checkbox. Unfortunately, same error
After some more searching on Google and the Sophos community I found https://community.sophos.com/kb/en-us/124585 which stated some possibilities why it could go wrong. This made me thinking, I was unsure of how many NICs I had configured, I remembered having played around with some setups. Because of my current setup I was sure I had at least 3 active NICs. So I retraced the above mentioned steps with 3, 4 and even 5 NICs… Same results.
Another thing I'm unsure about, is the RED interface, I've had it running in the past, but for the last year or so it's turned off, the KB doesn't clearly state if it counts a RED interface... I used the same serial number to register all installation as I had used within the backup configuration. Because I started with SFOS 17.0.6 MR-6, there was not yet the possibility to encrypt the configuration, so that should not be factor. In my last attempt I noticed that at step one ( entering a new Admin password ) there is an options to reload a config file, tried many backup files: same error
Anybody with suggestions, or things to try I haven thought of, would be much appreciated.
Thanks!
