Set Access

The set access command gives users at other nodes access to your backup versions or archived copies.

You can also use the set access command to give users at other nodes access to your backup images.

You can give another user access to a specific file or image, multiple files or images, or all files in a directory. When you give access to another user, that user can restore or retrieve your objects. Specify in the command whether you are giving access to archives or backups.

Windows operating systems Linux operating systems For VMware virtual machines, you can give a user at another node access to the backups of a specific virtual machine.

When a node is exported to another IBM Spectrum Protect server, the access rules can change on the importing server. If an access rule is applied to all file spaces on the exporting server, the access rule on the importing server is restricted to only those file spaces that are imported. The file spaces are restricted in the access rule on the importing server for security reasons. Additionally, the access rules do not recognize the first occurrence of a wildcard character in the file specification when you restore or retrieve. This means that if you restore or retrieve with a wildcard character in the file specification, subdirectories are ignored.

Tip: If you export a node to another IBM Spectrum Protect server, do not use a single wildcard character as the file specification in the access rule. Instead, create an access rule for each filespace.

Note: You cannot give access to both archives and backups using a single command.

Mac OS X operating systems Windows operating systems When an existing file space is renamed during Unicode conversion, any access rules that are defined for the file space remain applicable to the original file space. However, new access rules must be defined to apply to the new Unicode file space.

Supported Clients

This command is valid for all clients.

Syntax

Parameters

Archive

Permits access to archived files or images.

Backup

Permits access to backup versions of files or images.

filespec

Specifies the path, file, image, or directory to which your are giving access to another node or user. Use wildcard characters to specify a group of files or images, or all files in a directory; all objects in a directory branch; or all objects in a file system. Use a single asterisk "*" for the file spec to give access to all files or images owned by you and backed up on the server. When the command set access backup "*" node is entered, no check is made with the server; it is assumed you have at least one object backed up.

If you give access to a branch of the current working directory, you only need to specify the branch. If you give access to objects that are not in a branch of the current working directory, you must specify the complete path. The file spec to which you gave access must have at least one backup version or archive copy object (file or directory) on the server.

To specify all files in a named directory, enter /home/mine/proj1/* on the command line.

To give access to all objects below a certain level, use an asterisk, directory delimiter, and an asterisk at the end of your file spec. For example, to give access to all objects below home/test, use file spec home/test/*/*.

Important: Use of the form /*/* alone will not give access to objects in the named directory; only those in directories below the named directory are accessible.

The rules are essentially the same when considering the root directory. Enter /* on one set access command and /*/* on another if you want another user to have access to all files and directories in and below the root directory. The first /* gives access to all directories and all files in the root directory. The second /* allows access to all directories and files below the root directory.

For example:

Your directory structure is multilevel: /home/sub1/subsub1.
The /home directory contains the h1.txt and h2.txt files.
The /home/sub1 directory contains file s1.htm.
The /home/sub1/sub2 directory contains the ss1.cpp file.

To allow access to all files in the /home/sub1/sub2 directory, enter:

  set access backup /home/sub1/sub2/* * *

To allow access to only those files in the /home directory, enter:

  set access backup /home/* * *

To allow access to all files in all directories in and below the /home directory, enter:

  set access backup /home/* * *
  set access backup /home/*/* * *

filespec

Specifies the path, file, image, or directory to which your are giving access to another node or user. Use wildcard characters to specify a group of files or images, or all files in a directory; all objects in a directory branch; or all objects in a drive. However, you cannot use a wildcard to specify all drives. Use a single asterisk "*" for the file spec to give access to all files or images owned by you and backed up on the server. When the command

set access backup "*"
node

is entered, no check is made with the server; it is assumed you have at least one object backed up.

To specify all files in a named directory, enter d:\test\mine\proj1\* on the command line.

Important: Use of the form \*\* alone will not give access to objects in the named directory; only those in directories below the named directory are accessible.

The rules are essentially the same when considering the root directory. Enter \* on one set access command and \*\* on another if you want another user to have access to all files and directories in and below the root directory. The first \* gives access to all directories and all files in the root directory. The second \* allows access to all directories and files below the root directory.

Note:

Use the file space name if the drive label name has changed.
If you include filespacename, do not include a drive letter in the file specification.

For example:

Your directory structure is multilevel: d:\test\sub1\subsub1.
The d:\test directory contains the h1.txt and h2.txt files.
The d:\test\sub1 directory contains file s1.htm.
The d:\test\sub1\sub2 directory contains the ss1.cpp file.

To allow access to all files in the d:\test\sub1\sub2 directory, enter:

  set access backup d:\test\sub1\sub2\* * *

To allow access to only those files in the d:\test directory, enter:

  set access backup d:\test\* * *

To allow access to all files in all directories in and below the d:\test directory, enter:

  set access backup d:\test\* * *
  set access backup d:\test\*\* * *

{filespacename}

Specifies the file space name (enclosed in braces) on the server that contains the files to which you are giving access. This name is the drive label name on the workstation drive from which the file was backed up or archived. Use the file space name if the drive label name has changed.

image-fs

The name of the image file system to be shared. This can be specified as an asterisk (*) to allow access to all images owned by the user granting access.

-TYPE=VM vmname

This parameter is required if you are using this command to provide another user with access to VMware virtual machine backups. The vmname option can be specified only if -TYPE=VM is specified; vmname is the name of the VMware virtual machine that you are permitting access to.

node

Specifies the client node of the user to whom you are giving access. Use wildcards to give access to more than one node with similar node names. Use an asterisk (*) to give access to all nodes.

user

This is an optional parameter that restricts access to the named user at the specified node. To allow any authorized user to access your backed up or archived data, specify root as the user.
