Best Email Backup Software for Amazon S3

MultCloud allows you to sync two cloud services at once or two folders from different cloud accounts. Scheduled sync can be set up to automatically sync data between clouds at a specific interval. MultCloud will connect all your clouds. You'll be able to access all your online files from one login. Just like Windows Explorer, you can upload, download, cut/paste, paste, preview, rename and preview your online files. You can even "expand" your cloud storage by integrating multiple cloud drives. MultCloud runs the transfer process, so data can still be transferred even if your device is powered off. Because it is an offline cloud sync or transfer you can shut down your browser and computer once you have launched data transmission.

Backup data to local drives, network drives, Amazon S3, WebDAV, and FTP servers. The incremental backup will only backup the files that were changed since the previous full backup. You can restore any full or incremental archives at any time by using a few simple clicks.
