Qlik Replicate: task unable to read striped backup file

Alan_Wang — Fri, 07 Nov 2025 12:43:01 GMT

An SQL Server backup file is considered striped if it consists of multiple files or if it was generated from multiple files appended into a single bak file.

This means the backup files will contain the same LSNs for each of those files.

Qlik Replicate cannot process these multiple files with the same LSN.

The following error will occur when Qlik Replicate encounters striped backup files:

00012300: 2025-11-04T20:22:28:558929 [SOURCE_CAPTURE ]E: do_log_processing_direct(...) 2 multiple family members (=stripes) encountered in backup set while only 1 can be handled. [1020440] (sqlserver_log_processor.c:4685)

Resolution

Skip the LSN and start from another LSN or timestamp. Note that this will lead to a data gap for the LSN that was skipped.

You can also choose to do a full reload.

Cause

Striped backups are a result of SQL Server configurations. Please consult with your DBA on backup configurations.
