Symptoms

Linux File system permission of the NMC staging directory, nmcdb_stage,  changed to 700 after NMC backup.

Cause

This is working as designed and is expected behavior. The NMC backup process "savepsm" must set permissions on the NMC database backup stage folder as 700.

Notice the misconfiguration in save set field for NMC client resource as below.

Example:  

nsradmin> sh name; save set; backup command
nsradmin> . type: nsr client; name: <NMC client name>
name: <NMC client name>;               
save set: /nsr/nmc, /data01, /etc/hosts;
backup command: savepsm.sh;

Resolution

WARNING: Do not put any file system as save set in the NMC client configuration. It should only contain the absolute path to the nmcdb_stage directory.
  1. Allowed files in NMC database backup save set as per the command reference guide (savepsm - process used to perform backup in NMC database Backup) are:
  • NMC database
  • NMC database credential file (gstd_db.conf)
  • NMC lockbox files
  • Legacy authentication configuration files

Example: 

name: <NMC client name>;               
save set: /nsr/nmc/nmcdb_stage;
backup command: savepsm.sh;   
  1. Revert the file system permission to its original setting.

Example: 

# chmod 644 /etc/hosts
# chmod 755 /data01
