NBU 7.5 System disk incremental backup in openvms
- NBU 220.127.116.11
- OpenVMS: 7.3
- cliente NBU OpenVMS: 7.0.1
Current situation is that we can perform full and incremental backups in a file system correctly. However, when we try to perform incremental backups in a system disk, it always backup the whole disk even when we use the /modified parameter.
As long as I know, the /modified should onle backup the files that have changed since the last backup based on the delta time, so it should work correctly. I have been reading thorugh the manual, and I can't see anywhere that you cannot do incremental backup in system disk, or that you have to perform any extra action or add a new parameter to do them.
Could anyone confirm that they've done incremental backup in system disk, and the command that they have used to do it?
We use the following commands:
- Full backup up:
backup /policy=VMS /schedule=DIA <device_to_backup> /EXCLUDE=(*.SYS)/FULL
- For incremental:
backup /policy=VMS /schedule=DIA <device_to_backup> /EXCLUDE=(*.SYS)/MODIFIED
And both times NBU backups up the whole disk.
Can you see anything wrong with the commands?
