Backup Tapes
Text - AM Text tape and SM Text tape at the same software update level
ODD - AM ODD tape and SM ODD tape(s) at the same RC level.
5.10.3 BACKUP LEVELS
5.10.3.1 General
There are four levels of backups possible in the 5ESS switch 5ESS-2000 switch, depending upon the type of disks
equipped. These levels are as follows:
(1)
Memory to primary-disk backup
(2)
DMERT operating system root partition to backup-root partition
(3)
Office dependent data (ODD) backup to tape
(4)
Full office backup to tape or disk
The four backups listed are identical for the 340-MB, and SCSI disks. Only a general description of these backup
methods is provided in this section. For detailed procedures covering the 340-MB, and SCSI disks, refer to Memory
Alteration Procedures (Section 6 ).
5.10.3.2 Memory (core) to Primary Disk Backup
This backup is done any time changes to the office text or data are made permanent. This includes software
updates and data base recent changes. The data base recent changes consist of ODD and equipment configuration
data (ECD). It consists of saving the changes from memory to MHD 0 and 1. When the memory changes have been
made permanent, they are available on disk for automatic recovery situations which require booting.
5.10.3.3 DMERT Root to Backup-Root Partitions
This backup is performed prior to making changes permanent to data, program, or other files in the DMERT root
partitions (/dev/root, /dev/db, /dev/etc, and /dev/boot). These changes are the result of software updates or ECD
recent changes. The term primary partitions refers to the root partitions listed in Table 5-3 . This backup consists of
copying the partitions shown in Table 5-3 from the primary to backup partitions. Files in these partitions are
identified by pathnames that begin with something other than /no5text.
Table 5-3

/dev/boot
/dev/bboot
/dev/root
/dev/broot
/dev/etc
/dev/betc
/dev/db
/dev/bdb
Normally, system operation is performed from the files in the root partitions. This is indicated by the emergency
action interface page having item 31 (BACK_ROOT) cleared. Backup-root partitions are used only for recovery
situations. This means that if backup-root is used to perform recovery operations, the required corrections should be
made to the root partitions and control of the system must be returned to the root partitions. No ECD recent changes
or software updates should ever be applied to the system while it is running on the backup-root partitions.
