So we have one ex4100 now with 4 drives each 4tb with striping so we have 12tb capacity. I have one share that is 5.7TB and have been backing it up to a 8TB USB drive. But now the backup is failing and all I can tell is the dreaded “Backup Failed” - Backup failed. Please check your system settings. Backup Type Synchronize
Lots of searching shows it might be a known issue with USB backups and the total backup being large. So I thought this is not good that this is still a “known issue” with no fix but now might be the time to get a second one to remote back up to or clone it.
Anyone using a second ex4100 for back up or I would like to just run it as a remote clone so that both have exact copies of the data for redundancy.
