BACKUP and RESTORE Programs
BACKUP and RESTORE Programs
Private Copies of BACKUP and RESTORE
AutoSYNC makes use of the NonStop server’s BACKUP and RESTORE system
utilities. BACKUP is executed on the source system; RESTORE is executed on the
destination system.
In some operational environments, access to these programs is restricted. To use
AutoSYNC, you may need to obtain, license, and secure separate copies of BACKUP
and RESTORE.
You specify the alternate program names through the BACKUP and RESTORE
options.
Number of Files per BACKUP Process
BACKUP performance degrades significantly when the number of files is large. To
avoid performance degradation and limits in the BACKUP program, AutoSYNC
restricts the number of files it assigns to any one BACKUP process. AutoSYNC starts
multiple BACKUP processes, in sequence, to process all the files it is synchronizing.
The default number of files per BACKUP process is 1000.
You can configure the maximum number of files for each BACKUP process with the
MAXBACKUP option.
Reporting Outcome of the Synchronization
For a one-time synchronization, AutoSYNC writes status information to a temporary log
file and, when the synchronization is complete, summarizes the results. Specify the
LOGFILE option to retain the log file.

The LICENSE and PROGID attributes apply to object files. They are managed
carefully by the NSK file system to preserve system security. The basic security rules
that apply to all operations, including those performed by AutoSYNC, are as follows:
