Indexing media

Normally volumes, drives, folders or tapes are indexed and the metadata is stored in the database after a copy completes.
However you can also index drives or tapes and add then to the database without copying them.

Select a project

Open an existing project or click the project menu button to add a new project.

Add a new project

YoYottaID will automatically create a new project ID or you can enter your own ID. The project ID or # can contain letters and numbers Then enter a project name and click OK. In this popup panel there is also a remove project button.

Index and Verify media

Whenever a copy is completed metadata about the assets on the source and destination media are added to the database. If you just want to index tapes or drives there are two ways, automatic indexing and manual processing.

Make sure all your drives have unique names. This makes it easier to locate them manually or when using the Conform option. Also when two drives with the same name are mounted at the same time macOS will change the mount point which will stop you restoring files using the database or Conform option.

Auto Index : Whenever you add a new source drive YoYottaID will index all the files. If you add a tape then it won't be indexed immediately, however you can start the index by clicking the refresh button above the Job table.
Normally you would also have Extract Metadata, Make Thumbnail turned on and Add to Database turned off. Metadata includes timecode, codec and resolution and helps manual searching and also the Conform option. If you turn off Extract Metadata then you will still get the file name and size. If the source has a lot of files then turn off the Thumbnails. Extract Metadata can take a long time and could be turned off for multi TB volumes, however the metadata is stored as extended attributes so the next time the volume is indexed it will be much quicker.
When the backup of the source completes then this metadata will be stored into the database and the thumbnails will appear in the reports. The thumbnails are stored per project and the location is set in the Preferences panel.
If you have a lot of tapes or drives that you don't need to copy then turn on Add to Database. Now whenever you add a source it will be indexed and added to the database.
Auto Index will not extract metadata or make Thumbnails for LTFS tapes. Use the manual process below to index LTFS tapes. Tapes written by YoYottaID will already contain embedded metadata, so they will always index quickly.

Manual Index : Turn on Add to Database and click the Process button.
Extracting metadata and creating thumbnails from LTFS tapes will take a long time. You may want to turn these off.
If turned off then the file name, path and type will still be stored, but not the timecode, codec, resolution and other camera metadata.

The Process button can also perform a Quick or Full Verify of the source files.
The Quick Verify will check to see if the files have already been verified and also that they have not been modified since the verification.
The Full Verify will read back all files.
Both verification will work automatically if the media was created using YoYottaID. If the media was created using another system then the verify will look for md5sums.txt files in each folder.
If the source hasn't been created using YoYottaID then the Quick Verify will read all the files and create a checksum. This is useful if you think a source drive may be corrupted as you can test for this before starting the backup.

Connect a drive or tape

Add as a source to YoYottaID, click the refresh button to start tape indexing, then when indexing is complete click the database icon at the bottom of the screen.


All the media assets are shown in the table and you can search and export using the asset menu button. If the drive or tape was created onset using YoYottaID then it will have embedded MD5 metadata. This means that you can reverify using the original camera checksums. Also you can make MD5, ALE or CSV files at any time in the future.

YoYottaID LTFS + LTO Tapes

The database will include all the LTO tape metadata as well as the information for video, audio and metadata files.

Moving media metadata to a new project

Add a new project, select the old project, select the media and click Move Media to current Project.
This can be useful if media is indexed into the wrong project.
