want to save the access time for files and directories, you can pass the

Backing up full security descriptors on Windows is only possible when the user
has ``SeBackupPrivilege``privilege or is running as admin. This is a restriction
of Windows not restic.
If either of these conditions are not met, only the owner, group and DACL will
be backed up.
Note that ``restic`` does not back up some metadata associated with files. Of

* File creation date on Unix platforms
* Inode flags on Unix platforms
* File ownership and ACLs on Windows

By default, restic does not restore files as sparse. Use ``restore --sparse`` to
enable the creation of sparse files if supported by the filesystem. Then restic
will restore long runs of zero bytes as holes in the corresponding files.
