About Standalone Image Backup

[Lionel Liu]

Hello there,

We have two VMS cluster nodes share disk storage. Can we boot those two nodes in
standalone way with CD to do the image backup
at same time. We want to use this way to save time to do image backup.

Thanks very much

Lionel

Lionel,

You can do standalone backup at the same time. Of course you must have two tape devices which you can access from the nodes. Backup uses disks in read only mode.

Hm, does BACKUP automatically mount an input-disk read-only?

Anyway, I would manually mount the disks in read-only mode for BACKUP - especially if I boot from CD or don't have loaded any cluster code.

Last time I accidentally booted a second system without clustering it badly corrupted the system disk. It was good that I took a BACKUP before starting ;-)

But you don't want to corrupt your disks *while* backing up any data, do you?
