i'm trying to backup my data by just copying the files to another HDD but it's taking ages and sometimes the speed stops at 0 bytes and then it goes back to 400 KB/s and up (1MB+)
is this the safest way to backup my data?
Edit: also the time remaining says 1 day then 20 hrs, then again 13 hrs and so on (i know this isn't accurate, but still)
