As you can see, Patch B transforms Build 39216 into the most reliable version of Acronis True Image 2021.

Note: As of late 2022, Acronis moved on to True Image 2022 and then to Acronis Cyber Protect Home Office. Build 39216 Patch B is no longer the latest version, but it remains fully functional and supported for existing license holders.
Some users experienced “sync stuck” issues when backing up to Acronis Cloud. This patch resolves threading conflicts in the cloud synchronization engine. | Feature / Fix | Build 39161 (Initial)
If you already own this version (build 39216), definitely apply Patch B – it fixes real annoyances.
If you’re buying used/old stock, ensure the license key is valid and not blacklisted.
For new users today, consider Acronis Cyber Protect Home Office (2023/2024) instead, but build 39216+PB remains a capable, reliable backup tool – especially for local disk imaging.
Rating: 4.2 / 5
(Safe, stable, but dated subscription model and cloud speed keep it from 5 stars.)
