Documentation/git-bundle.txt: discuss naïve backups

It might be naïve to think that those who need this education would end up here in the first place. But I think it’s good to mention this high-level concept here on a command which provides a backup strategy.

347 +DISCUSSION
348 +----------
349 +
350 +A naive way to make a full backup of a repository is to use something to
351 +the effect of `cp -r <repo> <destination>`. This is discouraged since
352 +the repository could be written to during the copy operation. In turn
353 +some files at `<destination>` could be corrupted.
354 +
355 +This is why it is recommended to use Git tooling for making repository
356 +backups, either with this command or with e.g. linkgit:git-clone[1].
357 +But keep in mind that these tools will not help you backup state other
358 +than refs and commits. In other words they will not help you backup
359 +contents of the index, working tree, the stash, per-repository
360 +configuration, hooks, etc.
361 +
362 +See also linkgit:gitfaq[7], section "TRANSFERS" for a discussion of the
363 +problems associated with file syncing across systems.
