Ontape backup file naming conventions
What is the naming convention used for files in the ontape backup directory?
The directories specified using the ONCONFIG parameters TAPEDEV and LTAPEDEV provide the target location for ontape level 0 backup files and logical log backup files, respectively. In order to avoid duplication and assure unique filenames, a specific naming convention is used.
The filename used for file backups is
Day= Day of week
Mon=3 letter month name (in english)
hh= 2 digit hour (24 hour format)
mm=2 digit minute
ss= 2 digit second
Year= four digit (Gregorian) calendar year
XXXXXX is a unique OS generated string
Also, temporary file names may be visible until a backup completes.
'ONTL_'+<filename> == indicates a logical log file backup in progress.
'ONTA_'+<filename> == indicates a level 0 file backup in progress.
Note: Time references are derived from the system timestamp.
