Hello Drobo Community,
I’ve been using a Drobo 5N for the last ~5 years or so, very successfully backing up my multiple mac computers to separate TM enabled partitions.
After my recent upgrade to Catalina I noticed I lost access via the TM UI, my backups prior to Catalina went back to 5/2019… after the upgrade i could only view backups on stored locally, even tho TM would complete successfully and save data to the drobo.
After each patch pushed by Apple I would again loose visibility into backups prior to the update.
I’ve attached a detailed thread on my experience in the Apple Community forum. I’ve also submitted a feedback ticket to Apple (FB7400866) and they’ve requested detailed logs from Time Machine which I sent on 11/6, no response yet.
If anyone else is having a similar experience I’d like to hear it. From what I’ve read it sounds like Catalina has to ‘upgrade’ the backup volume and I don’t know if the Drobo is handling that task appropriately. I’ve noticed recently the backup volume in the Drobo Dashboard hanging while mounting. I’ve had to reboot the drobo to resolve this and notice immediately after rebooting I can see my May 2019 snapshots in the TM UI.
If I can provide any additional detail or expand on any of the points covered please let me know, I’ve provided extensive background on my experience in the link provided as well.
