What Is Backup and Restore Manager?

Backup and Restore Manager provides an GUI utility allowing users to easily write files or whole filesystems to tape, and later restore them to disk on the same or another system. B&RM can be launched from the Toolchest on most workstations.

For those who need to backup many IRIX systems, or want more in-depth information about backups and filesystems, the IRIX Admin: Backup, Security, and Accounting guide.

Note that SGI also offered a version of the Legato NetWorker backup management system to customers. While not covered on this page, you can review the Administrator's Guide on TechPubs. Note that NetWorker is now owned and offered by EMC; more information is available on the EMC NetWorker site.


How to Use Backup and Restore Manager

Users should read the Backup and Restore Manager section of SGI's Personal System Administration Guide. It describes how to use the B&RM tool, and how it can be used to schedule automatic and unattended backups. Other sections of the PSAG provide general background information about tape storage devices, filesystems, and other useful information.

Reading Backup and Restore Manager Tapes on Non-IRIX Systems

Even when the tape format used is commonly found on other UNIX systems, such as cpio or tar, there is sometimes a difference in byte ordering between the file- or tape-format used by the two systems. This can often be dealt with by using the dd utility to perform a byte swapping operation prior to reading the tape or file. For example:

% dd if=/dev/nrst0 conv=swab | tar xf -

Users may also need to pay attention to differences in the version of tar used on different systems. If tar is not natively available, there may be a version of pax available, or the user may be able to download and compile a viable version. Also note that tar may be present under the name "gnutar" or "gtar" on some systems.
