During the image migration step in a NetBackup 7.5 upgrade, client subdirectories in the image database directory that are linked at the file system level (UNIX/Linux; ln -s) (Windows; mklink) and do not have an alias or client name defined in NetBackup may have their *.f removed.
db/images/ClientA is linked to:
If ClientB has valid images but has not been backed up or defined by bpclient as an alias, the image cleanup process will incorrectly remove ClientB *.f files which results in the image no longer being browsable in the Backup, Archive, and Restore GUI. The image header is not expired so the media which contains the backup will not be overwritten.
Additionally, on Windows masters using the ALTPATH functionality:
If ClientA has not been backed up or defined, the image cleanup process will incorrectly remove the ClientA *.f files which results in the image no longer being browsable in the Backup, Archive, and Restore GUI. The image header is not expired so the media which contains the backup will not be overwritten.
The initial image migration upon upgrade to 7.5 through 220.127.116.11 was not properly adding the symlink/ALTPATCH client name to the alias list during catalog migration.
Customers who have experienced the issue on 7.5 GA- 18.104.22.168 can upgrade to 22.214.171.124 and restore the needed .f files from a catalog backup.
The formal resolution for this issue (Etrack 2847261) is included in the following release:
- NetBackup 7.5 Maintenance Release 4 (126.96.36.199)
