How many copies of ChromeOS does a ChromeOS device maintain at any given time?

ChromeOS maintains two copies of the operating system on the device: thecurrent versionand abackup version. This dual-system setup ensures that if an update fails or becomes corrupted, the device can fall back to the previous working version.

Verified Answer from Official Source:

The correct answer is verified from theChromeOS Update Management Guide, where it clearly states that ChromeOS devices store two versions to facilitate seamless updates and quick rollbacks if needed.

"ChromeOS devices store two versions of the OS. During an update, the new version is applied to the inactive slot while the current version remains active."

This redundancy allows ChromeOS to switch between versions without requiring a full system reinstall, maintaining uptime and stability.
