incremental backup seems very slow

in doing an incremental backup with version, it seems so slow

i’ve backed up lots of stuff and i cleaned out tons of stuff from my old backup source to help reduce what gets backed up, but an hour after starting it was still finding files, was at around 16.8 GB

is there a way for it to just start copying stuff without indexing(?) all files (if that’s even the right way to say it) ?
