Description
We have introduced a stability bug in version 7.1.28 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 Edit a Database for the steps to set DB parameters.
Fix
The stability issue has been fixed and remote backups work as expected.
