Invalid State

In Veeam Backup for Microsoft 365, a backup repository can be put into the Invalid state in any of the following cases:

• A repository lock in an object storage repository is missing.

A repository lock means that this object storage repository is in use by a backup proxy server or a backup proxy pool. Access to the object storage repository metadata is limited. A lock file is saved to the RepositoryLock directory. For more information, see Object Storage Repository Structure.

• A trusted certificate for S3 Compatible object storage repository has been changed.

• If any of the following is true for an object storage repository:

• A connection to an object storage repository is missing.
• A container or bucket is missing or has been renamed.
• A repository folder is missing or has been renamed.

• A connection to DAS or NAS is missing.

Such an invalid backup repository becomes available after your DAS or NAS is online.

Once a repository is put into the Invalid state, back up to or restore from such a repository is impossible.

Invalid backup repositories can be found in the Backup Infrastructure view under the Backup Repositories > Invalid node.
