...rt --from-files alphabetically, due to its use case with LTFS media. LTFS is a linear media with exceedingly slow seek times when compared with raw read/write speed. To do efficient reads, each file on the tape must be read off in the order it was written. Each file has an extended attribute (ltfs.startblock) which returns its exact location (startblock) on the tape. In this manner, you can easily obtain a list of files in the optimal order for reads (sorted, ascending, in order of their startblock). rsync's behavior of copying all files on and off in alphabetical order works fine if all you ever...
