Version: V8.4-2L1
Facility: Backup
Wanting: To produce a journal file from a backup operation
I tried...
$backup/journal=journal file_list/input_files saveset.bck/save
but alas, for some reason, backup doesn't want to produce a journal file when you use the /input_files qualifier (why oh why not, since the journal file appears to be populated when the saveset is closed anyhow ???)
The /input_files list contains wildcard selection, which is generated by a previous operation that selects files based on data record update date, which backup does not seem to support directly (unlike the directory command that does. again, why oh why can backup not support data record update dates directly?)
This is yet another example of how VMS file redirection is somewhat lacking (IMO), but this is another topic I guess. If directory output could feed backup as part of a backup input parameter it sure would make things easier /Gripe switch: OFF
So, how can I then create a journal file from a backup saveset (since it doesn't seem to support journal file creation with the /input_files qualifier (unless I am doing it wrong?)
I tried backup/list/journal=journal saveset/save NL: but backup bawks at my use of the NL: device because it is not part of a saveset in itself
So, is there:
1. A way to generate a journal file from backup using the /input_files qualifier ? (my preferred option)
2. A way to generate a journal file from backup saveset by doing a second backup pass operation over the saveset (rather I/O wasteful IMO)
Note: I have not used backup for years!! Data protector has ruined all my ancient operator backup experience, so sorry if the answer is simplistic because I just don't see it...
