|
|
|
|
SL::File::Backend::Filesystem - Filesystem class for file storage backend
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
See the synopsis of L<SL::File::Backend>.
|
|
|
|
=head1 OVERVIEW
|
|
|
|
This specific storage backend use a Filesystem which is only accessed by this interface.
|
|
This is the big difference to the Webdav backend where the files can be accessed without the control of that backend.
|
|
This backend use the database id of the SL::DB::File object as filename. The filesystem has up to 1000 subdirectories
|
|
to store the files not to flat in the filesystem.
|
|
|
|
|
|
=head1 METHODS
|
|
|
|
See methods of L<SL::File::Backend>.

=head1 TODO
|
|
|
|
The synchronization must be tested and a periodical task is needed to synchronize in some time periods.
