[OpenAFS] how to restore data from multiple incremental dumps

[Tom Jones]

Hi

 

We have OpenAFS 1.2.111-rhel3.0.1  on Redhat Linux 3.0.1. Since there is no direct TSM client available, we are using butc to dump data to local disk backup data file and then archiving to TSM server using TSM B/A client.

 

We are taking full dump on Saturday and differentail incremental dumps on Mon,Tues,Wed,Thursday.

 

/dev0sat  expires in  17d
    /dev0mon  expires in  16d
        /dev0tues  expires in  15d
            /dev0wed  expires in  14d
                /dev0thur  expires in  13d

 

How to restore data dumped on Wednesday? Accodrding to documents

 

backup volrestore -server <servername> -partition <partion name>
           -volume <volsetname> -portoffset a b c d

where port offset "a"   points to  fulldump backup data file

                             "b" points to incremental backup data file  (Monday)

                             "c" points to subsequent incremental data file (tuesday)

                             "d" points to subsequent incremental data file (wednesday)

 

However, when i run this command, command exists after restoring full dump i.e port "a"

Command is not even checking ports b,c,d. Is there any know bug?

 

Please suggest how to restore differentail incremetal dumps.

 

I successfully tested progressive incremental dumps restore, i.e one Full and one incremental dump using  MOUNT option.

 

Any word on direct TSM client for OpenAFS backups on Redhat Linux??? This will be great relief......

 

Thanks much

 

Tom
