I have to copy (periodically) a MSSQL backup file large 500 GB to another pc (windows or linux) within lan.
The normal copy (or xcopy, robocoy, teracopy) command to a network share (or external usb disk) takes a lot of time (about 12 hours) and the server with the backup file become very slow (because there is only one RAID SAS controller).
An "idea" maybe to split the backup file into smaller parts (like torrent) and copy these parts concurrently, but I don't know how to do it.
My primary target is to copy without impact the source server.
Any idea or tool suggested will be appreciated.
