Hi @JoaoJandre Performed my earlier tests, seems end of chain set for full snapshots is fixed now. Create & restore snapshot operations works fine with normal/full & incremental snapshots. Noticed incremental snapshots taking more physical size as earlier (you mentioned [here](https://github.com/apache/cloudstack/pull/9270#issuecomment-2334007857), these are the extra bytes to store the metadata, but it varies - please check/confirm). ``` Snapshot physical size diff (incremental - full): (ROOT-3-incr-file3 - ROOT-3-file3) = (2854486016 - 1694826496) = 1159659520 (ROOT-3-incr-file14 - ROOT-3-file14) = (6072369152 - 1529544704) = 4542824448 (DATA-3-incr-file3 - DATA-3-file3) = (1168048128 - 24379392) = 1143668736 (DATA-3-incr-file14 - DATA-3-file14) = (4630446080 - 85721088) = 4544724992 ``` <img width="1159" alt="full-and-incr-snapshot-records-new" src="https://github.com/user-attachments/assets/3465f8ad-7c2a-4e57-9847-e08897486221"; /> Note: A file added with 300MB for each snapshot taken. Incremental snapshots with _incr_ name are taken with _kvm.incremental.snapshot_ true, and _snapshot.delta.max_ set to 3.
