Description

We have introduced a stability bug in version 8.29.0 for remote backups using the FTP/FTPS and SMB protocols. On these affected systems, the backup can no longer be written and will abort just before the last write operation. The problem particularly affects systems with a large number of nodes and systems with large amounts of data.

Workaround

On some systems the remote backup functionality worked again with this additional DB parameter: "-backupAbortCheckTimeout=3600". Please refer to articles devoted to Database Parameters in section Database Management for the steps to set DB parameters.

Fix

The stability issue has been fixed and remote backups work as expected.
