KLS Backup review
A Windows-focused backup suite with broad storage, database, and scheduling support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
KLS Backup is Windows backup and synchronization software for individuals and organizations. It covers local and network files and folders, cloud storage, supported databases, mailboxes, and application data. The software supports Windows 10, Windows 11, and Windows Server, making it a fit for users who need scheduled protection for files and business data within a Windows environment. It is a paid product and does not include a free plan.
Its strongest area is destination and workload coverage. Backup jobs can target local or network locations, Microsoft Azure, Amazon S3, Google Cloud Storage, OpenStack, OneDrive, Dropbox, Google Drive, FTP, SFTP, WebDAV, and optical media. Database and application-data integrations include Microsoft SQL Server, MySQL, MariaDB, Microsoft Outlook, and Mozilla Thunderbird. Full, incremental, and differential backups are supported, along with archive version management, archive search, selective file and folder restoration, two-way synchronization, logs, and email notifications.
Security and administration features add control for scheduled operations. AES archive encryption protects stored backup archives, while SSL/TLS supports remote transfers. The Professional edition adds a command-line interface and web monitor, which suit organizations managing backup jobs through scripts or centralized oversight. KLS Backup is a strong choice for Windows users who need varied destinations, application-data coverage, and configurable backup types. It is less suitable for mobile environments or buyers seeking a free plan, and users whose primary requirement is disk-image recovery should evaluate whether its documented file-and-folder restoration meets their needs.
