Notes on Legato Networker Restore Operation - 1

Performing Recoveries from Command Line

 

Networker recover command

 

The recover command runs in two modes:

 

• Interactive mode � Interactive mode is the default mode for the recover command. This mode places you in a shell-like environment that allows you to use subcommands. These commands let you navigate the client file index to select and recover files and directories.

 

• Non-interactive mode (-a option) � In non-interactive mode, the files specified on the command line are recovered automatically without browsing. To activate non-interactive mode, use the �a option.

 

Using recover in Interactive Mode:

 

Login to the server you need to recover the file for and then type recover.  This will place you in the recover shell environment.  You can also type recover  [pathname] to set your initial working directory (recover /etc), the default is the current working directory.

 

[root@legatounixmst /]$recover

recover: Current working directory is /

recover>

 

[root@legatounixmst /]$recover /etc

recover: Current working directory is /etc/

recover>

 

*Note: If you do not get a recover prompted when you type recover, add a �s servername option.

 

[root@legatounixmst /]$recover  -s legatounixmst.itd.bnl.gov

 

 

The following commands let you navigate and client file index to select and recover files and directories.

 

Option	Description
ls	Lists information about the given files and directories. When no name argument is provided, ls lists the contents of the current directory. When you specify a directory as name, the directory�s contents are displayed.
cd	Changes the current working directory to directory. The default is the directory in which you executed recover.
pwd	Prints the full pathname of the current working directory.
add [name.. ]	Adds the current directory or the named files or directories to the recover list. If a directory is specified, it is added with all of the subordinate files to the recover list.
delete [name..]	Deletes the current directory or the named files or directories from the recover list. If a directory is specified, that directory and all of the subordinate files are deleted from the recover list.
versions [name..]	List all available versions for a file or directory. If no name is given the current working directory is used.
changetime	Change the backup browse time to recover files before the last backup. You will be prompted for new time. Time can be entered as December 15, 2004 or 12/15/2004.
list	Displays the files on the recover list.
recover	Recovers all files on the recover list from the Networker server. Upon completion, the recover list is empty.
exit	Exits immediately from the recovery
quit	Exits immediately from the recover. Files on the recover list are not recovered.

 

 

 

Using recover in Non-interactive mode:

 

In non-interactive mode, the files specified on the command line are recovered automatically without browsing. To activate non-interactive mode, use the option.

 

Examples:

 

Recover the /etc/hosts file from the most recent backup

 

recover  > /etc/hosts

 

 

Using the recover Command in Directed Recoveries:

 

To relocate recovered files use the �d destination option with the recover command. 

 

Examples:

 

To direct recovered files to /restore directory in interactive mode

 

               recover  -d /restore

 

To direct the recovery of /etc/hosts file to /restore directory in non-interactive mode

 

               recover  -a -d /restore /etc/hosts

 

 

[root@legatounixmst /]$recover -a -d /restore /etc/hosts
