I just bought an EX2 to store my time machine backups. My macbook pro runs Catalina. The time machine / EX2 combination is completely broken. The initial time machine backup works well, but the second backup never finishes. I tried to reinitialise the NAS three times, to no avail. Looking at tmutil status during the second backup, it copies millions of empty files and makes essentially no progress. It should not take multiple days for this second iteration. My EX2 is completely useless, since I bought it for this specific purpose. Has anybody else experienced this or a similar issue? Thanks in advance.
