i tried to backup my mac to my external hdd using time machine but it throw an error message
Time Machine could not create a local snapshot to back up from.
i've looked at terminal using terminal using this line
and it shows couple things but on other discussion they said just delete it using
sudo tmutil deletelocalsnapshots yyyy-mm-dd-xxxxxx
which i did but until now i'm still unable to backup my mac
i've tried format my backup using Mac OS Extended (Journaled) format and tried backup without encrypting it but same error message
i'm running macOS Catalina 10.15 on MacBook Pro 2016 13inch 512GB 4GB RAM
