We have a group of users who have a unique backup need.
They want to ensure that if a file gets deleted on their end, that it will never be removed from the backup. Due to the nature of their department, a deleted file could go unoticed for a long period of time and by the time they notice the file is missing it has already outlived our oldest date of retention.
Is there any type of backup/script/3rd Party solution anybody knows about that would just backup the files that have changed without removing missing files from the backup?
I appreciate it.
