Data export frequency in salesforce?

Hi Saurabh,

Data Loader is great tool for data management - included data export.

You can generate backup files manually once every six days (for weekly export) or 28 days (for monthly export). Salesforce creates a zip archive of CSV files and emails you when it's ready. Exports typically finish within 48 hours of submission, and large exports are broken up into multiple files. Follow the link in the email or click Data Export to download the zip file. Zip files are deleted 48 hours after the email is sent. The 48-hour time limit doesn't include weekends, which means if your download file is ready on Thursday at 4 p.m., that file isn't deleted until Monday at 4 p.m.

Thanks.
