Hi.

We accidentally unlinked our audit table in synapselink for dataverse. Now we lost all data stored by synapselink from over 6 months and have been deleting data from d365. Is there anyway to recover the parquet files automatically created by synapselink or is our data gone forever.

    Hello Jani,

    Did you confirm whether the Azure Data Lake Storage Gen2 account, where Synapse Link stored the Parquet files, still exists? Because if the storage account hasn't been deleted, the Parquet files might still be intact.

    Also, check if any data retention or deletion policies were configured on the storage account. ​

    If you have backups of the storage account or have enabled Azure Backup for the storage account, you might be able to restore the deleted Parquet files.​

    You may need to contact Azure Support promptly. They can assess if there's any possibility of data recovery.
