This is going to be a little confusing, but thanks to @Rusty I finally had HB backing up my source nas to a destination nas nightly, working 100% no issues. BUT then I had a raid pool issue the other day on my TARGET nas and the raid pool had to rebuild 1 drive because it reported crashed (long story, just work with me). OK. It did the rebuild and came back all good. The system was my Target NAS (with HyperBackup Vault) backup device. Now my Source says in HB couldn't connect to the target server, so I re-login thru HB to authorize the Target - which is on my LAN btw, which failed for some reason? So then I load the Target DSM page and it tells me its had 10 failed attempts and has blocked the IP of my Source nas! That was funny to me.
SO... I whitelist/allow the IP of my Source nas, on the security tab of my Target nas (which I never had to do before, I obviously know the login since I opened DSM). I try to re-login/authorize my Source nas to Target nas via HB (which btw only worked for me in Chrome, not Firefox? Must be an add-on or something I have in Firefox?) and now it says it cannot verify the integrity of the backup (failed to run backup integrity check). And now I'm stuck. The Target has my existing backup in HBV, I see the files, but I am not stuck at can not run backup integrity check. Now what?
