Skyvia allows exporting your backed up data to CSV files. The easiest way to Export your backed up data is the following:
Open the Backup Details Page for the backup you want to export data of and click Export links for objects you want to export data from.
If you need more advanced data export functionality, you can create a Backup Connection and use an Export Package to export your backed up data. Export packages allow selecting which fields to export and configuring filters for data to export. Export package is also the only way to export large binary fields from a backup (for example, this is the only way to export backed up Salesforce attachments).
