| Hi,
There is a cooklist on how to improve OpenVMS Backup performance.
It is based mainly in username account quotas (WSQUOTA, BYTLM, ...)
Is this still valid when doing backups with ABS ?
I ask this because I remember something in the past with SLS having
a special backup image with WSQUOTA 'hardcoded', so no influence when
changing username quotas.
Regards
Alberto
