We have recently confirmed a critical issue related to virtual machine backups on Hyper-V 2016/2019, due to a bug in the handling of RCT (Resilient Change Tracking) data, AhsayOBM is not able to correctly detect the block level changes on the virtual machine during an incremental backup. Even though AhsayOBM reports the backup job is completed successfully, all Hyper-V 2016/2019 incremental backups are no longer restorable.
Partners are strongly advised to immediately:
1. If your current AhsayCBS version IS NOT AhsayCBS v8.5.0.127 or above, then upgrade your AhsayCBS to v8.5.0.127 first. Please refer to the following KB articles for upgrade instructions:
2. If your current version is already AhsayCBS v8.5.0.127 or above, then simply apply the latest hotfix AhsayCBS v8.5.0.150 or above from the partners portal. Please refer to hotfix upgrade instructions: https://www.ahsay.com/partners/en/home/index.jsp?pageContentKey=ahsay_assets_hotfix-v8 (a valid partner portal account is required)
