This is on a 6TB WD MyCloud single disc that I purchased in January 2016 to backup my iMac with Time Machine.
Last week I discovered that my phone wasn’t backing up to this any longer so checked for firmware updates - none available. I’ve sorted this out but in the process had to reboot the NAS to get the phone to connect again. It then found a firmware update so I installed it.
After the update was completed Time Machine threw up an error saying that the username and/or password were invalid for the backup disc. The only way I knew of sorting this was to re-select the device from Time machine which, as on 2 or 3 previous occasions, caused it to ignore he existing backup and create a new one. Left it running overnight. Checked it next day and there is no sign of the new backup and Time Machine is now showing details of the previous backup. After nearly 24 hours there is no sign of the backup it was creating.
Did a quick and then a full diagnostic test which again ran overnight, spending a long time at 90%, but was eventually successful.
Got round to trying another backup
19:02 Preparing Backup: 5.02 TB available of 5.83
22:25 Backing up 316.4 MB of 14.15 GB
06:00 Backing up 691.4 MB of 14.15 GB 24/05/20
08:20 Backing up 910.4 MB of 14:15 GB
10:00 998 MB
17:45 1.12 GB
Rather slow.
Also I was getting “The operation can’t be completed because the original item for “TimeMachineBackup” can’t be found” when using Finder to show the share details. I also got this when trying to connect to a Linux PC share via Samba but got around this by using Cmd-K in Finder to bring up a share dialogue and connecting from this. 1.6GB copied from Linux to iMac in 20 seconds, so network ok.
Questions
- I am guessing that auto updates have caused the previous occurrences of the username and password issues and me reselecting the TimeMachine disc. Is there a way to reconnect to the existing share and avoid losing the previous backup?
- I have read that slow backups and the “operation can’t be completed” error can be related to the wrong protocol being used. Is there a way to check this before applying the fix?
- If the two issues aren’t related, is there a way to use Cmd-K to connect to Time Machine without having to create a new backup?
Many thanks
