Versions:
cv4pve-autosnap 1.21.0, published by Corsinvest Srl, is a command-line utility designed to automate snapshot management within Proxmox VE infrastructures. The tool addresses the need for reliable, policy-driven protection of virtual machines and containers by scheduling and pruning snapshots without manual intervention. Administrators can target specific guests through flexible patterns—ranging from individual VM IDs or names to entire resource pools—while defining separate retention rules for each label, enabling distinct daily, weekly, or monthly snapshot cadences under a single configuration. Pre- and post-snapshot hook scripts can be invoked, allowing quiescing of databases or application-level preparation before the checkpoint is taken. A built-in clean command removes expired snapshots according to the configured retention matrix, whereas the status command provides an overview of existing checkpoints across the cluster. Released as the fifth iteration in the series, cv4pve-autosnap continues to evolve within the virtualization backup & replication category, offering Proxmox users a lightweight alternative to heavier backup suites when only short-term rollback points are required. The software is available for free on wget.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
