I currently have our server backup on a daily basis to an external USB hard drive. I have made the disk visible in Windows Explorer by using disk management and assigning it a drive letter. I am trying to copy the folder on the USB hard drive that contains all of the backups to another external drive that gets brought off site every night, but I get the error "cannot read from source file or disk". I have checked the disk and there is nothing that I can find that would prevent copying (bad sectors, disk errors, etc...), this leads me to believe there must be a service accessing these files even when there is no backup in progress.
Does anyone know what services I need to pause or what I should do to make these files copy over completely?
Thank you!
