If you found this question while looking to deliberately separate and recombine metadata/file contents then you might want to take a look at metastore which is in the Ubuntu repositories.Ĭp from GNU coreutils >= 8.17 and above will work as described, but coreutils While this mirrors how cp behaves if you copy files into an existing tree, it might not be what you expect.Īlso note that if you didn't preserve hard links the first time around with rsync but want to preserve them now then cp won't fix that for you you're probably best off rerunning rsync with the right options (see my other answer) and being patient. destination/Īs with files, cp is additive with extended attributes: if both source and destination have extended attributes it adds the source's extended attributes to the destination (rather than deleting all of the destination's xattrs first). In this situation you probably want GNU cp's -attributes-only option, together with -archive, as it's tried and tested code, does all filesystem-agnostic attributes and doesn't follow symlinks (following them can be bad!): cp -archive -attributes-only /source/of/failed/backup/. BetterZip makes it easy to work with zip, rar, 7-zip, tar, and xz files. WARNING: Without special workarounds, GNU cp -attributes-only will truncate the destination files, at least in Precise. BetterZip: the most advanced zip and rar archiver for file compression, encryption. tells you in exhaustive, if terse, detail. If in doubt as to what rsync is copying that is taking so long, rsync -archive -dry-run -itemize-changes. Provided that updating the destination files' contents is acceptable, or if the source files are untouched since the original copy, you should find rsync -archive -size-only quicker than a naive rsync. A Better Finder Attributes 5 that concentrates entirely on EXIF Photo file date changing. This, plus the fact that -whole-file is implied for local->local syncs, makes rsync without -times approximately equivalent to cp for local syncs.

Without external guarantees from you that the source files' contents haven't changed, rsync has to assume they might have and therefore has to checksum them and/or copy them to the destination again. Without -archive (specifically, without -times) the destination files' mtimes remain set to the time you rsync-ed them, while the source files' mtimes remain intact (ignoring manual trickery by you). Rsync usually uses equal mtimes as a heuristic to detect and skip unchanged files. Treating the question as "rsync only has metadata to copy, so why is it so slow, and how can I make it faster?":
