Veeam Backup And Replication Overflow Error -

temporarily if the overflow occurs during compression phase.

Reported in the Veeam console during active jobs.

Use multiple NAS backup jobs splitting the share by path or file mask.

Ensure your backup repository storage volumes (especially ReFS or XFS) are formatted with a 64KB block size . veeam backup and replication overflow error

: For Linux agents, this can often be fixed by modifying the veeam.ini file to increase the max snapshot space or changing the snapshot location to a drive with more free space.

During the backup of a Virtual Machine, the Volume Shadow Copy Service (VSS) or the hypervisor may return a metadata value (like a disk offset) that triggers an overflow in the Veeam transport service. Common Scenarios and Solutions 1. SQL Database Limitations (Express Edition)

:

Protecting massive virtual machines (VMs) with thousands of incremental restore points creates enormous metadata files. When Veeam processes these deeply nested dependency chains, the metadata size can overflow the allocated RAM cache or memory tracking buffers. 3. Repository Scale Obstacles

Veeam tape jobs tracking catalog data across hundreds of LTO tapes can trigger overflows during catalog indexing if the number of recorded file parts hits a hard database ceiling. Scale-Out Backup Repository (SOBR) Offload Overflows

Fixing the error gets your backups running today, but structural adjustments ensure your infrastructure remains stable moving forward. Implement Per-Machine Backup Chains temporarily if the overflow occurs during compression phase

If you’ve checked your database and updated your software but still see the error, it’s time to and open a ticket with Veeam Support, as there may be a specific hotfix required for your unique storage hardware.

: If using SQL Express, migrate the configuration database to a full version of SQL Server or Veeam's PostgreSQL-based engine (introduced in v12) to remove the 10 GB limit.
