SnapBack DOS: Various Out of Memory Conditions.

• Run the DOS program MEMMAKER to increase the

amount of available conventional memory.

• Append /overlay=40000 (or less) to the SnapBack

command line. This will reduce the conventional memory

requirement at the expense of execution speed.

SnapBack DOS says “Incorrect block size e0200000”

when at start or restore.

When doing a disaster image restore from SNAPBACK/

DOS you may need to modify the block size of the tape.

This should only be necessary when the tape’s Block Size

has been changed in the SnapBack Configuration or

automatically when the backup was made. The block size

used on the backup will be recorded in the SnapBack log

file.

Execute SnapBack DOS using the BLOCKSIZE command

line with a value matching the size used when the backup

was created. To set the blocksize to 512 bytes run SnapBack

using the command line:

SNAPBACK /BLOCKSIZE=512

If the log file is not available try to restore using the values

32768, 512, and 1024. These are the most common block

sizes.
