Upgrade - How to roll back

guardian

I am currently running 2.4.3-RELEASE-p1, and I see that older versions are no longer available, so I can't reinstall the old version.

Can someone please give me some suggestions on a fallback strategy in the event my upgrade kills my router. If that happens I will be cut off from the internet completely, so it is essential that I have whatever I need to get back up and running immediately.

Is it safe to create a tar.gz file of / - it's not an atomic transaction? If so what about restoration?

Hello,

make a backup (Diagnostics/Backup&Restore/Download configuration as XML)
download 2.4.4_p1 image and make bootable USB stick. With 2.4.4_p1 release, FAT32 partition will be created on USB stick, so you can put your XML configuration file into this partition.
upgrade and check if it works
if it isn't, reinstall from USB stick

Thanks @asamat - Hopefully I won't need to roll back, but at least I know one way to do it.

The system came back up. Only thing is the console froze with:
Booting

The little spinner didn't spin and I got no boot messages.
I did a second reboot and see if the issue would clear, but unfortunately it didn't.

I'll post this as a separate thread.
