Slowness with NAKIVO Backup & Replication jobs
If you experience slowness with NAKIVO Backup & Replication jobs, you can localize the problem and reveal its cause by taking the following steps:
- Identify the route that your data takes to get transferred from the source to the destination. Define the source Transporter, the target Transporter, and any other intermediate components such as source disk, target disk, LAN or WAN.
Install a profiler which is a special component developed by NAKIVO for the Transporters involved in the data transfer route. You can download the profiler by following one of the links below:
For Transporters installed on Linux: https://d96i82q710b04.cloudfront.net/res/product/Profile/Ubuntu/bh
For Transporters installed on Microsoft Windows: https://d96i82q710b04.cloudfront.net/res/product/Profile/Windows/bh.exe
For Transporters installed on NAS devices: https://d96i82q710b04.cloudfront.net/res/product/Profile/NAS/bh
For Transporters installed on NAS devices with an ARM v7 processor: https://d96i82q710b04.cloudfront.net/res/product/Profile/NAS_armv7/bh
For Transporters installed on NAS devices with an ARM v8 processor: https://d96i82q710b04.cloudfront.net/res/product/Profile/NAS_armv8/bh
Stop all Transporters involved in your data transfer route. Make sure that these Transporters are not busy with jobs, and there are no repositories attached to them. Please refer to Starting and Stopping Product Services for details.
Locate the original
bhfile for your platform. The file default location is:
C:\Program Files\NAKIVO Backup & Replication\transporter\bh.exe
If you fail to locate the profiler in the default location on Linux and NAS devices, please use the following search command:
find / -name "bh" | grep transporter
Move the original
bhfile to a safe location, or rename it and move the previously downloaded
bhfile to the original location. Make sure that the file name is
If you use SAN transport mode, replace
bh-sanexecutable instead of
For Linux, change permissions for the new
bhfile by running the following commands:
chmod +x bh
chown bhsvc:bhsvc bh
When ready, start the Transporter service for all previously stopped nodes.
Run your backup or replication job.
When the job is complete, create a support bundle and send it to NAKIVO Technical Support. It will take some time to analyze your support bundle and provide you with a technical support summary. Based on the provided technical support summary, you will be able to identify and fix any bottleneck in your virtual infrastructure.
Finally, you will need to revert the previously applied changes back. To do this, follow the procedure below:
