replicate/copy only missing files to remote server

[vandammages]

Hi,

 

I am looking for what you gents recommend to do backups/replication  on unraid 6.01

I have 2 unraid 6.01 servers in 2 diff locations.

 

I want to copy only files on Serve A from  Shared folders to Server B Shared Folders. ( New or older files)

Only Files that server B does not have should  be copied from server A .  Compare and add what is missing. (compare by file name)

also If server A deletes files .. nothing happens on Server B.

If server B has files server A does not.. do nothing.

Looking to have this automated as well.

 

any suggestion appreciated
