I have been using a bare metal Hyper Backup from a DS1522+ to a DS420+, both in my home, succesfully for more than a year now. Both systems are fully updated. Recently, without any change from my part, Hyper Backup stopped working as target is listed as Off-line, although it is indeed online and I can normally connect to it.
Anyone having similar issues? It’s a 26tb backup and I want to avoid doing it from scratch.
Let me guess: you open the task settings of the backup task in Hyper Backup, you enabled transfer encryption and the certificate is not trusted. This halts the backup. Trust or Pass (I am not sure of the exact words) and the target comes online again.
And again, I have made no changes whatsoever, be it in the settings or hardware of either NAS or network equipment (the internet provider’s default switch/router). The destination NAS is also online and functioning normally.
I just changed the target server name to the local IP address and it worked, it sees it as online now and it’s backing up. Why would it stop working out of blue though? The server name is still the same.
