NAME
RT::ExternalStorage::Disk - On-disk storage of attachments
SYNOPSIS
Set(%ExternalStorage,
Type => 'Disk',
Path => '/opt/rt4/var/attachments',
);DESCRIPTION
This storage option places attachments on disk under the given Path, uncompressed. The files are de-duplicated when they are saved; as such, if the same file appears in multiple transactions, only one copy will be stored on disk.
The Path must be readable by the web server, and writable by the sbin/rt-externalize-attachments script. Because the majority of the attachments are in the filesystem, a simple database backup is thus incomplete. It is extremely important that backups include the on-disk attachments directory.
Files also must not be modified or removed; doing so may cause internal inconsistency.
