Configuration Restore Fails With: "2200N: invalid XML content DETAIL: buffer full"

Last update date:


Affected products:

Veeam Backup & Replication

Affected releases:


Fixed releases:

No fixed releases provided.



When performing a configuration restore or migration, the Restore process fails with the error: 2200N: invalid XML content DETAIL: buffer full Cannot read configuration backup


This error is caused by an underlying issue within PostgreSQL 15.1 and 15.2 PostgreSQL 15.1 was included with the following versions of Veeam Backup & Replication: Veeam Backup & Replication 12 P20230718 Veeam Backup & Replication 12 P20230412 Veeam Backup & Replication 12 P20230223 Veeam Backup & Replication 12 GA Veeam Backup & Replication 12 RTM   By default, PostgreSQL is used with all new installs of Veeam Backup & Replication 12. Existing Veeam Backup & Replication deployments that were upgraded from 11a or older will continue to use Microsoft SQL Server until they are manually migrated to PostgreSQL.


This issue was resolved in PostgreSQL 15.3. To resolve and prevent this issue, Veeam recommends all customers with Veeam Backup & Replication deployments using PostgreSQL 15.1 or 15.2 upgrade to the latest but we strongly recommend to download and install the latest PostgreSQL 15.x version.
