i apreciate you shared your method, i will look into LuckyBackup,
the way i copy my files is using cygwin with rsync , using a bash script with a list of directories to be sent to unraid,
once a month i just run the script and all the new/modified files are sent to unraid ,
also have a docker gitea in unraid to keep projects versioning
so i just let the unraid parity process to execute once a month and that way i spect to have redundancy of the files in my two unraid disks,
so its mostly an automated process
if i get a disk failure on my unraid box i hope i will be able to recover all the data either from the parity or from the data disk
and in the future feel free to delete files from my windows box knowing there is a safe copy on unraid
yes im not saving files history , i use the unraid box to store personal files from my main windows pc (with the risk you mention of corrupted files)
thank you for pointing that out
