/dev/rst12 -L 12N6J

Restore with Earlier AMASS Version

To recover data on a Backup Volume containing a backup from an earlier version of AMASS, make sure the current MAXIOSIZE parameter on AMASS is configured to the same value as when the Backup Volume was made.

For example, your current Backup Volume was made when the MAXIOSZ value on AMASS was 256 KB. (This value should be physically noted on the volume.)

Upgrade AMASS and change the MAXIOSZ value to 1024 KB.

Before attempting to read the Backup Volume, return the MAXIOSZ parameter on AMASS to 256 KB.
