File System Backups
File system backups are required to protect the Hitachi Storage Viewer application directories, files, and OS-specific settings, such as the registry and services for Windows. The file system backup should also capture the nightly database export, which resides in the file system.
HDS recommends that you utilize your company’s backup method of choice to perform the file system backup. While we recommend a full system backup, we have identified below the key files created or modified by Hitachi Storage Viewer.
HDS - Modified Files
• The file paths are shown with Linux usage. For the Windows path names, preface the path with C:, use backslashes instead of forward slashes (for example, C:\opt).
• Typically, you’ll have the reporting database located on the Portal server. If you are operating in a split architecture—that is, your database is on a server that is different from the Portal server—there may be some files from both servers that need to be backed up. Note that a split architecture is no longer supported and this information is for legacy environments only. If you have a split-architecture environment, see the comments in the following tables; however, we recommend that you contact Global Support Center to verify that you have the necessary backup coverage for the files that reside on the Portal server and on the Database server.

Note: When backing up the above directories, follow the symbolic links to back up the source directory.
For example: /user/java is typically a symbolic link to /usr/java_versions/jdk<version>
Other Symbolic Links
These symbolic links may vary in your environment. Check the Hitachi Storage Viewer Certified Configurations Guide for the latest third-party and open source versions.
tomcat --> apache-tomcat-5.5.25
openldap --> openldap-2.4.37
apache --> httpd-2.4.6
New Users and Groups
Users: aptare, tomcat (all part of /etc/passwd)
Groups: aptare, dba, tomcat (all part of /etc/group)
Note: Both /etc/passwd and /etc/group should be backed up.
