Hi @abrar,
The code that actually performs the file export is here:
The scheduler is here:
/opt/kaltura/app/batch/batches/Storage/KAsyncStorageExportExe.php
It is configured to run in /opt/kaltura/app/configurations/batch/batch.ini:
[KAsyncStorageExport : JobHandlerWorker]
id = 180
friendlyName = Storage Export
type = KAsyncStorageExport
maximumExecutionTime = 1800
scriptPath = batches/Storage/KAsyncStorageExportExe.php
params.chmod = 755
In terms of debugging, the best place to start is the logs under /opt/kaltura/log/batch. Each worker has its own designated log file.
