Error description
IBM Spectrum Protect Plus for Microsoft Exchange cannot backup more than 100,000 transaction log files. The backup operation may not complete due to a crash. Additionally the log files may grow to over 1GB Platforms affected: All Windows Initial Impact: --> 1
Local fix
Exchange transaction log files grow during normal exchange activities. Normal VSS backup operations will truncate the transaction log files. Having a SLA policy that will keep transaction log files under 100k will prevent the issue. The following cases have also been identified. Enabling circular logging during these cases will prevent the transaction log files from growing. Once they operations complete, disable circular logging. -Moving mailboxes from one database to another -Loading a database -Any time VSS backups have not been ran on a database for long period of time (Maybe weeks or months) For the above cases, perform the following: - Disable SLA backups for the database(s) - Enable Exchange circular logging - Perform the mailbox move or load operations - Disable Exchange circular logging - Enable SLA backups for the database(s)

The input/output json file * * will be very huge and it will cause exception when parsing * * the huge json file (it's a limitation of C# string). And * * also, the 100,000 log files caused a very huge command.log. * **************************************************************** * RECOMMENDATION: * * Apply fixing level when available. This problem is currently * * projected to be fixed IBM Spectrum Protect Plus level * * 10.1.4. Note that this is subject to change at the * * discretion of IBM. * ****************************************************************
Problem conclusion
In the fix, we support '*' in the input / output json, like one record 'E00*.log' for all log files. It will reduce the json file and command.log size.
