I am trying to configure backup for /ram (NFS Mount point), Backup job is completing successfully with below error. Please advice.

Netbackup Master server version : 7.1

Check netbackup client where the NFS fs is mounted, does have the Premission to the path /rman/backup/cfmemdb/

PS:- better option is to take the backup from the NFS server as a local file system, it avoids lot of issue, even data travel in the Network.

[Marianne · Accepted solution]

Check share permissions on source server as well as mount options on NBU client. 

Backup is running as root and will need sufficient permissions to read data.

Please do the following while logged in as root on the client:

ls -l /rman/backup/cshrddb/

Any reason why this filesystem cannot be backed up from source server?

Many thanks for your reply Marianne & Nagalla.

We didn't have all access to customer's client server, I had a discusstion with them and found out that it had to do with the permissions on the datafiles, They are owned by user oracle & they were on Mode 640 (USER-read/write, GROUP-readable, but not WORLD-readable)

The NetBackup client runs as root, but it is unable to read the files because, by default, root has no special permissions on this NFS mount.

Customer has change the way the /rman mount is exported, so that is has root permissions. Now I have kicked off the backup job which is picking up data :)

Now only below error is coming : 
 

01/16/2013 04:56:49 - Warning bpbrm (pid=16851) from client xxxxxxx: WRN - Could not reset access time of /rman/one. Errno = 1: Operation not permitted.

I believe for this we may want to add DO_NOT_RESET_FILE_ACCESS_TIME to client server's bp.conf file??

[Marianne]

Correct.

Cause

NetBackup cannot reset the File Access time back to the original setting

Solution

1- By Default NetBackup reset the access time of the file after reading/backing up the data BACKUPS.

   The default behavior is to reset access time of backups. (NetBackup stores access time prior to backup, then after backuping up the file , it resets the access to the original setting).

   Resetting access time is only valid if the following condition is set;

     - The NFS filesystem is not mounted with 'noatime' flag. This flags disable access time tracking for the filesystem.

       - The file System access permission is set for "root" user to read & write

2- The main reason for this message that NetBackup cannot reset the File Access time back to the original setting

      NetBackup does not have Write permission or the file system is mounted with 'noatime' flag.

3- The Best Solution is to allow NetBackup to reset access time i.e. modify the NFS File System setting to allow write access for root and disable 'noatime' flag.

4- If the Customer require to disable NetBackup from resetting the Access Time

      then there is an option which disable NetBackup Default setting by adding 'DO_NOT_RESET_FILE_ACCESS_TIME ' to the client's /usr/openv/netbackup/bp.conf file.
