Ellis,
First of all thank you very much for details. One question, i installed
Avamar and use for flat files as it is not supported for any database.
Networker 7.5 will be supporting oracle, exchange and sql, but not released
yet. Are you using Avamar? Have you ever tried restore from deduped SQL
backups?
Thanks & regards,
Mesut
