Metus INGEST saves the auto-split parts of the encoded video in local workstation, and in a few seconds after the encoding started, it will automatically start transferring the split files to final network location. There will be no loss of data even if the network shuts down, as the split files are cached in local workstation until transferring to network has completed successfully for each split part.
