The positive parts are:
- you don't have to "register" the catalog-tapes with hotbackup. Just inventory it.
- differential and cumulative incremental backups are possible now
- you use the whole tape. before only full backups were made and allways written at the begin of the tape
- if no catalog-tapes are available, the scratchpool-tapes where used
- handling is now via the catalog-backup-policy easier includet retentions etc.
Info: When you reuse the old catalog-tapes for the new hot-catalog-backup, you have to label these tapes again, because the magnetic media-id on the tape is "NetBackup" and won't be used for "normal" backups. But for this you have to uncheck the checkbox for "verify before performing label operation".
