Copy and Daily Backup
Copy Backup
In Copy Backup, all selected files and folders are backed up. Copy Backup neither uses nor clears the archive attribute. Copy backups are not used for typical or scheduled backups. Instead, copy backups are useful to move data between systems or to create an archival copy of data at a point in time without disrupting standard backup procedures.
Daily Backup
All selected files and folders that have changed during the day are backed up based on the files’ modify date. The archive attribute is neither used nor cleared. If you want to back up all files and folders that change during the day without affecting a backup schedule, use a daily backup.
