Time Machine reports low space in MyCloud?

Time Machine reports low space in MyCloud, and could not finished a 160GB backup, but the MyCloud shows 886GB available? Does anybody know how to solve this problem?

Check the Time Machine setting in the My Cloud Dashboard > Settings section to ensure the Time Machine feature has access to the entire drive. If I remember right, one can limit/reduce the side of the available space the Time Machine can use.

Thanks! It is already in the max! But the time machine still are not performing the back by lack of space

If you are OK with Terminal commands try:

cat /etc/samba/tm_config.conf

and look at the max share size.
