Automatic unlimited file backup for one Windows PC or Mac per license What is Backblaze Computer Backup?
Backblaze Computer Backup is worth shortlisting for straightforward automatic file backup on a Windows PC or Mac. Flat per-computer pricing and unlimited eligible data reduce storage-plan decisions. Its limits are equally important: no NAS or Linux client in this product, no full-system image and no multi-computer coverage under a single license. Check retention and perform a restore test before relying on it.
Back up eligible files from a Windows PC or Mac continuously.
Include supported directly connected external drives, subject to drive and retention rules.
Select historical files and use documented client or web restore workflows.
Use 30-day history, enable one year free or choose paid Forever retention.
Vendor-documented encryption, optional private keys and two-factor authentication.
Open-source encrypted file snapshots with your choice of local or cloud storage Kopia is free, open-source backup software for encrypted snapshots of files and directories.
Kopia makes sense when you want encrypted file snapshots and control over your destination. Its software is free, but storage, credentials and restore testing are your responsibility. Choose a managed service instead if you want bundled cloud storage and less setup. This is a documentation-based assessment.
Back up selected files and directories with locally encrypted content and names.
Local/NAS, supported object storage, WebDAV and SFTP destinations; storage billed separately.
Set snapshot scheduling, exclusions, retention and compression.
Store content already present in one repository only once.
Restore files/directories, download individual files or mount snapshots.
Encrypted file backups to your choice of local or cloud storage Duplicati is a backup application that stores compressed, encrypted copies of selected files in a destination you choose.
Duplicati is useful for a storage-you-choose file backup plan. Start small, keep credentials and configuration outside the protected computer and prove recovery with a test restore. Compare total storage cost and database reconstruction effort, not only the free download.
Back up selected files to local storage or supported remote providers.
AES-256 or GPG options; passphrase recovery remains your responsibility.
Compression and deduplication reduce repeated transfers and storage.
Run jobs at selected times and configure how long versions remain.
Restore with destination credentials/passphrase even without the original local configuration.
