Densar BK
Densar BK backs up what git and file-sync tools leave out: the AI agent's memory, the junctions, the secrets and local configs. It scans the root folder and finds them by itself, then writes an encrypted archive (age standard, password required) and skips what can be rebuilt: in one real run, 0.38 GB archived against 21.73 GB of caches left out. On the new PC it does more than put files back: it recreates the junctions instead of duplicates that drift apart, remaps the agent's memory to the new paths, reinstalls the toolchain (winget, npm, cargo, pip), and lists the steps still missing to run each project. Since 3.0.0 it restores straight from your own server, guided, opens an archive like a zip to pull single files out, and carries the memory of Cursor, Gemini CLI, Codex CLI and Copilot next to Claude Code. Analysis is free and shows what would be saved before you decide. A backup is a one-time EUR 59. Restoring is free, on any machine, no licence. Windows only. Nothing leaves the PC.

Duplicacy
A new generation cross-platform cloud backup tool. Duplicacy backs up your files to many cloud storages with client-side encryption and the highest level of deduplication. Duplicacy is built on top of a new idea called lock-free deduplication, which works by relying on the basic file system API to manage deduplicated chunks without using any locks. A two-step fossil collection algorithm is devised to solve the fundamental problem of deleting unreferenced chunks under the lock-free condition, making the deletion of old backups possible without using a centralized chunk database. Duplicacy comes with a newly designed web-based GUI that is not only artistically appealing but also functionally powerful. With just a few clicks, you can effortlessly set up backup, copy, check and prune jobs that will reliably protect your data while making the most efficient use of your storage space. The intuitive dashboard includes several statistical charts.
