Resolved Issues

General

  • A retention processing bug may subsequently lead to a backup job failing with the error:
    Full storage not found
    
  • Replication jobs may fail due to the AUX data overflow when processing VMs with large Microsoft SharePoint servers.

Direct Restore to Cloud

  • Restore to Google Cloud Platform fails when the default VPC networks are missing.
  • Restore to Microsoft Azure may fail due to issues with disk allocation.

Microsoft Hyper-V

  • After a SureBackup job is completed, temporarily created VMs remain listed with a "Missing" status within SCVMM.
  • In rare circumstances, additional licenses were consumed for the same machine processed by two different backup servers managed by Veeam Backup Enterprise Manager.
  • Slow guest credential testing for Hyper-V VMs managed by SCVMM.

Backup Copy

  • Backup Copy Jobs operating in periodic copy mode may not release repository task slots, preventing other tasks from starting.
  • Backup Copy Jobs operating in immediate copy mode consume excessive resources.

Tape

  • An incremental NDMP job run on a small data set may fail with the following error:
    Failed to find NDMP environment variable
    
  • A connection drop occurring when a Backup to Tape job is exchanging tapes causes the job to fail with:
    Session key set is null
    
  • Backup to Tape jobs may freeze during the backup infrastructure resource allocation step.

Scale-Out Backup Repository (SOBR)

  • Enterprise Application Plug-In jobs fail due to inaccurate reporting of free space on SOBR extents.
  • Offloading backups from the Capacity to the Archive tier may fail with the following error:
    Target FIB already exists
    
  • Capacity Tier rescan fails when multiple copies of the same Plug-in for Microsoft SQL Server backup are present.
  • Connections to Amazon Glacier Archive Repositories are not proxied through the assigned gateway server.
  • Under certain circumstances, the capacity tier offload task may fail with the following error
    Error: Array dimensions exceeded supported range
    
  • The capacity tier offload task gets stuck when attempting to process orphaned backups.
  • In rare situations, the immutability of inactive backup chains is erroneously prolonged when it’s no longer needed.
  • Under certain circumstances, the backup server may overflow Amazon S3 and S3-compatible object storage with empty metadata files.
  • Slow enumeration performance for buckets containing more than 1000 backups.

Security

  • Veeam.Backup.ProxyProvider.dll does not pass the Strong Name Validation.
  • Backup server vulnerabilities: API Endpoints on port 9393 are accessible by users without any roles assigned on the backup server; DbProviderApi access control issue.
  • Veeam Backup Enterprise Manager vulnerabilities: REST API path traversal, access control issues for /api/FailoverPlans/getAll, Content-Security-Policy misconfiguration.

Veeam Cloud Connect

  • Jobs to cloud repository may fail with the following error:
    The string universal unique identifier (UUID) is invalid
    

NAS Backup

  • The “restore attributes” function does not restore the original attributes when using a NAS backup copy restore point as a source.
  • Some Backup I/O Control functionality settings may use more proxy resources than intended.
  • Rescanning NetApp Filer with a share name containing the ampersand (&) symbol fails with the following error:
    Unexpected end of file has occurred
    

Storage Integration

  • Storage snapshot cloning fails for NimbleOS version 6.1.2.0 and later.
  • Backup job from storage snapshots fails with the following error:
    Failed to parse block info XML document
    

VMware Cloud Director

  • Poor performance of quota management and resource allocation operations in large multi-tenant environments.
  • Under certain circumstances, backup jobs may get stuck at 99% completion.

Veeam Plug-ins for Enterprise Applications

  • On AIX systems, Veeam Plug-in for Oracle RMAN erroneously applies network throttling to networks not specified in the global network traffic throttling rules.

Veeam Backup for AWS

  • Excessive backup server resource consumption due to Veeam Backup for AWS not terminating Agent.PublicCloud.Satellite processes.

P20230227

  • Vulnerability (CVE-2023-27532) in Veeam Backup Service was fixed.
    This vulnerability was reported by Shanigen.

P20220302

P20211211

  • Microsoft Windows 11 and Microsoft Windows 10 21H2 support as guest OS, Hyper-V hosts (as a target for Instant Recovery and SureBackup), for installation of Veeam Backup & Replication components, and for agent-based backup with Veeam Agent for Microsoft Windows 5.0.2 (included in P20211211).
  • RHEL/CentOS/Oracle Linux 8.5, Ubuntu 21.10, Fedora 35 distributions are now supported as the guest OS for the installation of Veeam Backup & Replication components and for agent-based backup with Veeam Agent for Linux 5.0.2 (included in  P20211211). The latter also supports Linux kernel up to version 5.16 and no longer requires installing the linux-image-<version>-dbg package on Debian 11.
  • Oracle Database 21c support by application-aware processing of image-level backup including redo log backup, by Veeam Plug-in for Oracle RMAN 11.0.101.1264 (included in P20211211) and by Veeam Explorer for Oracle.
  • RHEL 8.4 for SAP Solutions and SLES 15 SP3 for SAP Applications support by Veeam Plug-in for SAP HANA.
  • VMware Carbon Black compatibility for vSphere VMs processing.
  • LTO-9 support. Tape jobs will now identify and display the media calibration process in the Action log and will no longer time out should this process takes longer than 15 minutes.
  • Platform: added API extensions enabling Kasten K10 integration and configuration backup/restore for upcoming versions of Veeam Backup for AWS/Azure/GCP; deleting cloud-native backup appliance will no longer delete the corresponding external repositories to facilitate configuration backup restore.
  • SOBR Capacity Tier: increased timeout for certain long-running object storage operations (like clean up) to 25 hours; fixed the root causes behind offload failures with “Block not found”, “The INSERT statement conflicted with the FOREIGN KEY constraint” and “No recovery record was found for storage key” errors.
  • Tape: fixed NDMP performance regression introduced in 11a; added support for Kasten K10 backups and backup copies to Backup to Tape jobs as well as support for restoring such backups from tape.
  • Microsoft Azure: region settings have been moved into the configuration file to allow for enabling Archive Tier functionality there as Microsoft rolls out the Archive Storage class to additional regions.
  • Microsoft Hyper-V: the presence of an empty SCVMM tag should no longer cause various issues in the related functionality; VMs from nested HostGroups should no longer be skipped from processing; application-aware processing failures on VMs with a very large number of network adapters.
  • VMware Cloud Director: the new plug-in version 11.1.7 adds support for: deployment with a very large number of organizations; LDAP-integrated users with multiple roles; installation side by side with other data protection plug-ins; browsers with the locale set to a language not present in the language picker.
  • Veeam Cloud Connect: evacuating backups of a particular tenant should no longer lock the entire SOBR extent preventing other tenants from accessing their backups; encrypted tenant backups should now be correctly unpublished following the restore from Archive Tier; tenants should again be presented with a choice of keeping or removing their replicas when removing cloud hosts.

P20211123

  • Scale-out backup repository (SOBR): initiating SOBR rescan with one of Performance Tier extents being in maintenance mode, and taking said extent out of the maintenance mode at the specific moment of the Rescan process results in all backup files on this extent replaced with stubs downloaded from Capacity Tier.
  • SOBR Capacity Tier: under certain circumstances,  copy/offload to Capacity Tier starts failing with the “Attempt to overwrite existing non-sparse block version” error.
  • SOBR Archive Tier: a rare situation involving an interruption or a failure of the S3 API call to object storage during the specific operation may place Capacity Tier into a state resulting in further Archive Tier offload attempts failing with the “Specified key does not exist” error.
  • Email notifications: backup job email notifications are missing information about datastores with a lack of free disk space.
  • User interface: some UI nodes may show outdated job status information, requiring users to press F5 to refresh the view and actualize it.
  • HPE StoreOnce: updated HPE StoreOnce Catalyst library to version 4.2.4, which includes a fix from intermittent “Pipeline hanged” errors when reading data from the corresponding backup repository.

Known Issues

Please consider the following prior to installing the cumulative patch:
  • Veeam Agent for Linux: version 5.0.2 comes with veeamsnap kmod/kmp modules signed with a renewed certificate. Following the agent upgrade, you must update veeamsnap-ueficert package and enroll the new certificate to UEFI MOK, otherwise the module will fail to load. This applies only to RHEL/CentOS and SLES/openSUSE machines with UEFI SecureBoot enabled.
  • Veeam Cloud Connect: backup and backup copy jobs containing Windows 11 Hyper-V VMs and Kasten K10 backups will start failing for tenants if they install P20211211 before their service provider.
