2.4. Restoring Clips
2.4.1. Before Restoring
Before restoring a clip, verify if the clip has been tagged as archived and only contains a
low-resolution video file on the nearline storage. If you try to restore a clip the high-
resolution video file of which is still online, the clip will be moved to the Restore Rejected
bin.
2.4.2. Fully Restoring Clips
Introduction
Clips can be fully restored by dragging them into the Request Restore bin in IPDirector,
or by selecting the clips in the Hires Removed tab of the Deep Archive Manager and by
clicking the Restore button.
Workflow 1: Restoring Clips in IPDirector
The restore workflow in IPDirector proceeds as follows:
1. In the Database Explorer of IPDirector the user searches for the clips whose high-
resolution video file has to be restored to the nearline storage.
2. The user drags and drops the clips in the Request Restore bin.
If the Request Restore bin has been defined as the user default bin, the user can also
right-click the clips and choose Send to > Default Bin. See the IPDirector user
manual for more information about setting a particular bin as default bin.
3. IP2Archive Communicator which continuously polls the Request Restore bin detects
the clips and enters the restore requests in the IP2Archive database. It moves the
clips to the Restore in Progress bin.
4. In the Deep Archive Manager the clip appears in the Restore Queue tab.
5. Deep Archive Controller picks up the restore requests in the IP2Archive database. It
checks if a HSM is available, and if this is the case, assigns the restore requests to it.
It then commands Tape Storage Controller (DIVArchive, FlashNet, ADA) or File
Transfer Daemon (XenData) to initiate the restore process.
6. Tape Storage Controller and File Transfer Daemon request the HSM to start the
restore process.
7. The high-resolution video files are restored from LTO tape. DIVArchive, FlashNet and
ADA will restore the files directly to the nearline. XenData will restore the files to its
cache. File Transfer Daemon will then transfer the files to the nearline storage.
During the restore process, IP2Archive Communicator provides feedback to
IPDirector by updating the clip archive metadata. If anything goes wrong, the clips will
be placed in the Restore Failed bin.
