Networker - some savesets not visible when browsing in GUI for recovery
Product:
Networker 7.6.2 on Windows 2008 R1 Server
Networker Module for SAP (lgtonmsap-4.1-1)
Networker Client (lgtoclnt-7.6.2.1-1)
Problem description:
We have backed up Sap/Oracle database. We have konfigured and run:
- first backup = full backup of database (online mode ) + backup of
archive logs with delete option (this have copied and deleted archive log
files numbered up to 708)
- second backup = next day full backup of archive logs with delete
option (this copied log files 709 to 900 and deleted them)
Both retention and browse time are set for 14 days,
From perspective of SAP system, it all looks good - Archived Log files are
being deleted from directory after they are backed up.
But when we try to restore using Networker User, we cannot see all the
Archive Logs files that were deleted. Browsing the archive log directory in
recover window we can only see log files up to 177 and 808-900.
After changing Browse time to 12:20 AM (right before second backup) - the
files copied during first backup appear.
To be able to see and recover log files from second backup - I need to
change "Browse time" minute by minute across period that second backup
lasted - each time I can see different subset of backed up log files. Is
this correct functionality?
Still, some of these are not visible, no matter what browse time I set. This
is not matter of wrong browse time for these backup sets (I've checked
savesets retention times with mminfo -vV -o e -c client volume). Looks like
possible problem with index base, I've tried nsrck -L 6, but no result.
With a bit effort I can recover these missing log files, basing on save date
(obtained with nsrinfo -vV -N missing_file_name client) and searching for
correspondind ssid (mminfo -vV -o e -c client volume), then invoking at
client system: "recover -d /tmp/recover/ -S ssid -s server". So I'm sure
these log files are available and recoverable, but what is the reason I
cannot see them throug Networker User GUI?

Hi Bartuus,
Restoring NMSAP backups through winworkr is not supported. It might work- but you should use BRTools to perform the restores.
Also, I think what you are seeing in the GUI is expected behavior. Since the files are deleted after the backup (t1), they don’t exist during the next backup (t2). During a restore, winworkr shows the state of the system at a specific browse time. So if the browse time is set to t2 or higher, the files deleted as part of bkup t1 will not show up. Does that help?

SAP backups are done using BRTools. This means restore should be done via brrestore. You can use ssid restore if ssNameFormat set to old, but you would use that in specific cases only. The whole idea of online modules is that it integrates with application/database it backs up via given API and application/database backup framework is used for both backup and restore.
