Finding the aristos.cfg File
The aristos config file is located in one of the following two locations (if the agent was installed in the default location):
32-bit Systems: C:\Program Files\Replibit\aristos.cfg
64-bit Systems: C:\Program Files (x86)\Replibit\aristos.cfg
Before modifying aristos.cfg, make sure you stop and disable the Replibit service or the file will be write protected.
The default configuration is shown below:
Modifying Volumes to Backup
The BACKUP_VOLUMES= line of the config file is an inclusion list. By default, the list will be blank, prompting a backup of all detected NTFS volumes. To set your inclusion list, specify the volumes you would want to back up, separated with commas. Please see the below image for an example:
Modifying the Number of Worker Threads
As a default, Replibit is set to use 4 worker threads per processor core.
In some cases, you may need to reduce that number by manually specifying the number of threads. To modify the number of worker threads:
- Stop the Replibit service
- Open the aristos.cfg file with notepad
- Add the line NUM_WORKERS=X where X is the number of threads
- Save the file
- Start the Replibit service
Note: Lowering the number of worker threads will reduce the speed of the backup. If the backups start overlapping, you may need to increase the time between snapshots.
Enable/Disable Fast Delta
Fast Delta is a new, proprietary block change scanning tool that dramatically improves the backup performance of large database applications like Microsoft Exchange and Microsoft SQL. Enabling Fast Delta can reduce backup times from hours to minutes for larger Exchange and SQL deployments because the agent no longer has to scan the entire DB filesystem for changes not yet committed to VSS.
Note: Fast Delta is turned OFF by default. To enable Fast delta on any of your Microsoft SQL or Exchange servers exhibiting long backup times, enable fast delta by performing the following steps:
- Stop the Agent on the Protected System
- Edit the aristos.cfg file in the Agent installation directory
- Set USE_FASTDELTA=true (or false if you want to disable) and save the file
- Start the Agent service on the Protected System
