• Transactional transfer requires write permissions rename permission on the target host (to remove the atomic prefix / suffiux).
• Transactional transfer is is a two phase operation and is not 100% reliable - there are situations where rollback is not possible.
  Consider
  • For example, consider the situation where a
  large
  • number of files are transferred transactionally to a remote
  Windows
  • system,
  where renaming cannot rolled back
  • and update - i.e. overwrite - already existing files.

    • If,

    after transfer of all the files has been completed

    • during the rename/overwrite transfer phase, one of the files

    waiting

    • to be

    renamed is accessed

    • overwritten has been opened by another process

    on the target server (which should not but can happen) - the rename action will fail and the whole transfer should be rolled back

    • , access to this file will be denied and the transfer will fail.

    • The file copy or move transfer phase can be rolled back but the files that have been overwritten cannot be reverted to their previous state.
