What is the problem you are having with rclone?
I've got an admittedly unusual and probably not targeted use case for rclone, but I'm curious if it's possible to make this work.
I've got a batch of files that are being synced to LTO tapes (formatted as LTFS) from a remote source. The data spans multiple LTO tapes, and I don't have an autoloader, so it's impossible for all the synced data to be online at the same time.
As new data comes in, I'm copying the new files to whatever the latest tape is.
Normally, if the destination data was all online, I could just do a "sync" operation which would look at timestamps, hashes, etc. to automatically determine which files had changed / been created since the last sync.
In my case, though, I can't do a sync operation, because rclone will only see the files on the current tape and will try to sync any file that's not on that tape (even if it's present on another tape).
Is there any way, via rclone, for me to maintain something like a metadata-only backend that keeps a list of timestamps, hashes, etc. for all the tapes? Then, this could be consulted by rclone when I perform a sync operation, and only files missing from this metadata list need to be synced.
Or, is there any other good approach for doing this? It might be possible to do with timestamps (e.g., assume all files past a certain time stamp need to be synced, but I'm unfortunately not sure the timestamps are consistent on the source...)
