Hello Tiffany, assuming your repositories are SQL server databases, having database credentials,
For jobs export:
"%LINK_DIR%\bin\al_engine.exe" -NMicrosoft_SQL_Server -passphraseATL -U<UserName> -P<Password> -S<Host> -Q<Database> -Xp@J@"<FilePath>\<FileName>.atl"
For Dataflows export:
"%LINK_DIR%\bin\al_engine.exe" -NMicrosoft_SQL_Server -passphraseATL -U<UserName> -P<Password> -S<Host> -Q<Database> -Xp@D@"<FilePath>\<FileName>.atl"
Create a batch file with above two commands, append current timestamp to file name and schedule the batch file from task scheduler.
For more details on the command usage, execute "%LINK_DIR%\bin\al_engine.exe" from command prompt or refer attachment.
