I have about 592GB of data stored on a USB hard drive (not stick) which is my first backup location. I used the Copy command on the Web-gui to copy this to a Backblaze Bucket. There are about 120k chunks. At around 25k chunks it basically crashed and now I have to start again. Will it copy the first again all the chunks new or will it realise that they are already copied?? I have just invested in a 4 year licence and the ability for the Copy command to actually copy reliably the initial backup is crucial. Any help would be appreciated. Of course I cannot rule out network issues but surely it should be able to resume from the last copied chunk (what is the default behaviour here??).
Thanks for any help.
