This topic contains information about the NAS proxy configuration details, metadata, and log files for NAS devices and NAS shares.

NAS proxy log files

The NAS proxy log files contain details of backups that the NAS proxy performs. Every backup generates a new log file in the following format.

Hybrid Workloads agent

Log file format: Phoenix-<time stamp>-<job ID>.log
Example: Phoenix-20170921-152700-181.log

Enterprise Workloads agent

Windows: C:\ProgramData\Druva\EnterpriseWorkloads\logs\nas\backup{backupsetID}\{job_id}\nas_{job_id}.log
Linux: /var/log/Druva/EnterpriseWorkloads/nas/backup/{backupsetID}/{job_id}/nas_{job_id}.log

If the NAS proxy does not function as expected, you can share these log files with the Druva Support team.

Note: Druva retains logs for the last 32 NAS proxy activities on each NAS share. 

Log location on NAS shares

You can find the NAS proxy log files at the following locations:

Windows 2008, 2012, 2016 and 2019

  • C:\ProgramData\Phoenix\NAS\logs\backup\<backupset id>\<log file> (for agent version prior to 7.0.0)
  • C:\ProgramData\Druva\EnterpriseWorkloads\logs\nas\backup\<backupset id>\<job id>\<log file> (for agent version 7.0.0 and later)

CentOS, RHEL, SLES, Ubuntu

  • /var/log/Phoenix/NAS/backup/<backupset id>/<log file> (for agent version prior to 7.0.0)
  • /var/log/Druva/EnterpriseWorkloads/nas/backup/<backupset id>/<log file> (for agent version 7.0.0 and later)

NAS proxy configuration details

The configuration file contains the configuration details that the NAS proxy requires to communicate with the Druva Cloud. 

Configuration details on NAS share

You can find the NAS proxy configuration details at the following locations:

  • Windows 2008, 2012, 2016, 2019:  
    • C:\ProgramData\Phoenix\NAS\Phoenix.cfg (for agent version prior to 7.0.0)
    • C:\ProgramData\Druva\EnterpriseWorkloads\Config.yaml (for agent version 7.0.0 and later)
      This is the configuration file containing common information for all the activated workloads. 
    • C:\ProgramData\Druva\EnterpriseWorkloads\nas\Config.yaml (for agent version 7.0.0 and later)
      This is the configuration file specific for NAS.
  • CentOS,RHEL,SLES,Ubuntu: 
    • /etc/Phoenix/NAS/Phoenix.cfg (for agent version prior to 7.0.0)
    • /etc/Druva/EnterpriseWorkloads/Config.yaml (for agent version 7.0.0 and later)
      This is the configuration file containing common information for all the activated workloads. 
    • /etc/Druva/EnterpriseWorkloads/nas/Config.yaml (for agent version 7.0.0 and later)
      This is the configuration file specific for NAS.

Workload agent services

On Windows servers, NAS proxy Client Service manages backups and restores. The PhoenixCPH service (for Hybrid Workloads) or Druva-EnterpriseWorkloadsSVC (for Enterprise Workloads) on Windows servers ensures that the NAS proxy Client Service is running. On Linux servers, the Phoenix process ensures that NAS proxy is running. 

Note: If NAS proxy  stops working, PhoenixCPH (Windows) / Druva-EnterpriseWorkloadsSVC (Windows), or Phoenix (Linux) starts the NAS proxy. 

Frequently Asked Questions (FAQs)

How to automatically delete older job logs of a backup set on a NAS proxy during a backup or restore?

You can set the threshold value by using the OLDER_LOGS_DELETION_AGE parameter in the configuration file to delete older job logs, thereby saving space on the NAS proxy. The default value is 180 days. The minimum allowed value is 1.
