These backups as John did can be restored to a original volume without
problem, because the volume was already formatted.
To restore to a new volume, it MUST be CP-Formatted before the restore.
Use ICKDSF to format with the option CPVOLUME FORMAT.
Best regards.

I have successfully backed up and restored volumes containing z/Linux
data using z/OS and DFDSS. And example step would look something like:
//BACKUP EXEC PGM=ADRDSSU,
// TIME=NOLIMIT,REGION=2048K
//SYSPRINT DD SYSOUT=*
//DASD1 DD DISP=OLD,
// UNIT=SYSALLDA,
// VOL=SER=volser
//BACKUP DD DSN=hlq.BACKUP.V&VOLSER(+1),
// DISP=(NEW,CATLG),
// UNIT=CART,
// LABEL=(1,SL,EXPDT=99000),
// VOL=(,,,10),
// DCB=(BKUPSYS.MODEL,BLKSIZE=32000)
//SYSIN DD *
DUMP INDDNAME(DASD1) -
OUTDDNAME(BACKUP) -
TRACKS(0,0,3338,14) -
OPT(3) -
CPVOLUME -
ADMINISTRATOR
/*
This was for a 3390-3 volume, which has 3339 cylinders (0..3338). I
think why it worked for me was the use of the TRACKS parameter to dump
each track.
