Large File Transfers within ZimaOS

I have a 14TB external HDD and i want to copy everything to a new 14TB external HDD within ZimaOS. I am imagining this will take some serious time and i am concerned with interruptions. It would be nice if I could continue interrupted transfers. God forbid I have a power outage or something. I am also concerned with cpu usage and heat related concerns. It would be nice if there was a app or something that would work within ZimaOS to manage this large file transfer process. These are files i am using for Plex and Jellyfin so i would like to copy instead of cut and paste so i could keep everything running smoothly during this process.

any and all advice would be appreciated. Thank You.

I would try copying files in groups of maybe 10GBs or something like that. I have never had a problem uploading or downloading large files in ZimaOS.
