Overview
An access-control list (ACL) defines permissions for users and groups on NAS shared folders. Upgrading from ACL 1.0 to ACL 2.0 introduces stricter compatibility requirements for snapshot-related features in Snapshot Manager, such as SnapSync, Snapshot Replica, and importing snapshots. Inconsistent ACL versions between source and destination systems may block certain features.
Details
The following features and functions are blocked under the following ACL version mismatch conditions:
- SnapSync
SnapSync job operations are blocked when the ACL versions of the source and destination are different (e.g., one uses ACL 1.0 and the other ACL 2.0).
Blocked operations include creating, running, and editing SnapSync Jobs, and running performance tests.
Note
If both source and destination systems use ACL 2.0, but only the destination folder is still using ACL 1.0, then SnapSync job operations are still available. When the job runs, the destination folder will be automatically upgraded to ACL 2.0.
- Snapshot Replica
Creating and running Snapshot Replica jobs are blocked if the source uses ACL 2.0 and the destination uses ACL 1.0. - Importing snapshots
Users cannot import a snapshot from an ACL 2.0 system to a NAS that uses ACL 1.0.
When you try to perform any of the above operations, the system responds in one of the following ways depending on your firmware version:
| Firmware Version | System Response |
|---|
| QuTS hero h5.3.x or earlier | The system blocks the operation and displays a generic error message. |
| QuTS hero h6.0.0 or later | The system blocks the operation and displays a specific error message indicating there is an ACL version mismatch. An event log is also recorded, allowing users to troubleshoot later. |
Solution
- To ensure full compatibility with all snapshot operations, upgrade both source and destination NAS systems to ACL 2.0.
Note
QES does not currently support ACL 2.0. If your destination is running QES, you will not be able to upgrade its ACL to version 2.0.
- If upgrading is not possible, use ACL 1.0 for both systems, or consider alternative backup methods.

概述
访问控制列表（ACL）定义了用户和组对 NAS 共享文件夹的权限。从 ACL 1.0 升级到 ACL 2.0 引入了对快照管理器中与快照相关功能的更严格兼容性要求，例如 SnapSync、快照复制和导入快照。源系统和目标系统之间不一致的 ACL 版本可能会阻止某些功能。
详细信息
在以下 ACL 版本不匹配的情况下，以下功能和操作将被阻止：
- SnapSync
SnapSync 作业操作在源和目标的 ACL 版本不同（例如，一个使用 ACL 1.0，另一个使用 ACL 2.0）时被阻止。
被阻止的操作包括创建、运行和编辑 SnapSync 作业，以及运行性能测试。
注意
如果源和目标系统都使用 ACL 2.0，但只有目标文件夹仍在使用 ACL 1.0，则 SnapSync 作业操作仍然可用。当作业运行时，目标文件夹将自动升级到 ACL 2.0。
- 快照复制
如果源使用 ACL 2.0 而目标使用 ACL 1.0，则创建和运行快照复制作业将被阻止。 - 导入快照
用户无法从使用 ACL 2.0 的系统导入快照到使用 ACL 1.0 的 NAS。
当您尝试执行上述任何操作时，系统将根据您的固件版本以以下方式之一响应：
| 固件版本 | 系统响应 |
|---|
| QuTS hero h5.3.x 或更早版本 | 系统阻止操作并显示通用错误信息。 |
| QuTS hero h6.0.0 或更高版本 | 系统阻止操作并显示特定错误信息，指示存在 ACL 版本不匹配。还会记录事件日志，方便用户后续排查。 |
解决方案
- 为了确保与所有快照操作的兼容，请将源和目标 NAS 系统都升级到 ACL 2.0。
注意
QES 目前不支持 ACL 2.0。如果您的目标系统运行的是 QES，您将无法将其 ACL 升级到版本 2.0。
- 如果无法升级，请在两个系统上使用 ACL 1.0，或考虑其他备份方法。
