Sync is for the files you’re working on

Sync services keep current files aligned across devices and help with sharing and collaboration. Changes, including deletions, can propagate to other connected devices.

Many sync services offer trash recovery and version history. Their time limits, account requirements and recovery features vary, so check the terms of the service you use.

Backup is a separate recovery history

A versioned backup saves point-in-time copies. You decide where those backups live and how long to retain them, then restore a selected version when needed.

DiskPond backs up files and folders. It is not a live synchronization service, a full-disk image, or a bare-metal system recovery tool.

Think in independent copies

The 3-2-1 approach is a useful starting point: three copies, on two types of storage, with one copy off-site. The right setup depends on the value of your data and the failures you want to recover from.

An always-connected writable destination can still be affected by malware or compromised credentials. Consider a disconnected copy or provider-specific immutability where appropriate; do not assume encryption alone makes a backup immune to deletion.

Test the way back

Whatever tools you choose, periodically restore a few files into a separate folder. Keep encryption passwords and storage recovery information somewhere you can reach if your main computer is lost.
