Common errors Safe Mode in NetVault Backup

When using RDA for backups, only four streams are used at once

When using RDA to back up 20 or more clients, in device activity, only four streams are used at once. Updating the setting in the configuration file at /config/dellrda config file from 32 streams to 512 streams and restarting NetVault services, yields the same result.

When multiple backup jobs that target the same disk-based storage device are scheduled to start at the same time or within a small window of time, the following issues occur:

These issues occur because the Media Manager uses a “quiesce time” setting to prevent assigning too many simultaneous jobs to a disk-based backup device. By default, the quiesce time is set to 10 seconds. Thus, after a job is assigned to a disk-based storage device, the Media Manager waits for 10 seconds before assigning the next job to the same device. You can change the default setting for quiesce time in the mediamgr.cfg file.

Open the mediamgr.cfg file in a text editor.
You can find this file in <NetVault Backup home>\config on Windows and <NetVault Backup home>/config on Linux.

Note the following:

 

Safe Mode in NetVault Backup

The following error occurs when NetVault Backup is in Safe Mode, “NetVault Backup Server is in safe mode. Please contact your service provider.”

In this case tenant must contact MSP administrator.

The following error conditions can force NetVault Backup to run in Safe Mode:

In Safe mode MSP administrator must read the message from <Installation location>\config\safemode.cfg>, after login to NetVault Backup Server

This file keeps the cause of NetVault Backup Server to run in Safe Mode.

The following table describes the error types and possible options to resolve the issue identified in safemode.cfg:

Key process failures

When NetVault Backup enters safe mode due to this error, no options are provided to resolve the issue.

Database connection failures

Please validate PostgreSQL Service logs and resolve the issue. You can now restart the services, if issue persist contact NetVault support.

 

Low disk space issues

Reclaim space in NetVault Backup installation location and go to restart NetVault Backup in normal mode

Restart NetVault Backup in normal mode: Once NetVault Backup enters safe mode, it remains in this mode whether the error is resolved or not. To exit safe mode, restart NetVault Backup in normal mode.
Stop the NetVault Backup Process Manager and NetVault Backup PostgreSQL database server services. Remove safemode.cfg file from the following location: <Installation location>\config\safemode.cfg> and restart NetVault Backup PostgreSQL database server and NetVault Process Manager services.
Restart NetVault Backup with diagnostic tracing enabled: For diagnostic tracing consult Quest Technical Support.
