• viewing the backup data versions according to backup rule (manual
activation only)
Manual operation
FTP connection failure on a manual operation causes generation of the
proper SRPT system, providing the details of the failure (FTP server
unreachable, login name/password rejected, requested directory path not
found, or data transfer failed). The operation is aborted.
Automatic operation
FTP connection failure on automatic operation is automatically attempted
again for a hard-coded number of times (five) with a hard-coded delay (ten
seconds) between attempts.
An automatic operation FTP session occurs in sequential steps, such as
copying the file to the remote site, deleting and renaming operations for the
multi-version support, and so on. Any attempt to connect continues from
the step that failed during the previous attempt to connect. If connection
attempts exceed five, the proper SRPT system alarm report is generated
and the backup operation is aborted.
Defining backup schedules
• In LD 117, define a new backup rule (or rules) by using
NEW/CHG/OUT/PRT BKPR commands.
• In LD 43, verify the newly defined backup rules by performing manual
backup (
BKR R ), printing backup data versions ( DAT R, DAT R V ),
and manual restore ( RSR R ).
• In LD 117, define a new backup schedule (or schedules) with reference
to the newly defined and verified backup rules
(
NEW/CHG/OUT/PRT BKPS ).
• Wait for the scheduled time to occur.
Backup operations performed manually by entering the BKR command in
LD 43 (or configured in backup scheduler) provide multiple versions of the
backup data preserved on the storage device. These multiple versions
use incremental numbering.
When performing a manual restore by entering the RSR command in LD
43, the version of the backup data must be entered as a parameter. In
most cases, the latest version is chosen as version number one, but under
certain conditions, information about all stored backup versions may be
required. This query is provided by the enhanced
DAT (data versions)
command in LD 43.
