Question : Problem: How to backup data which is over 20 Gb ?

I have one NT 4.0 File server and to backup data from this computer to tape drive i used NT built-in backup tool and it is ok when i used it with 4/8 Gb tape drive/catridge.
But after i changed my tape drive and tape catridge to 20/40 Gb (20 no compression/40 with compression), the NT built-in backup tool can't backup data over 20 Gb ( the NT built-in backup tool doesn't support compression for 20/40 Gb tape).

So what software should i use instead of the current one ? or is there other way to do ?

Thanks,

I also think you should take a look at veritas. In this case Veritas Backup Exec 8.6 or higher would be suitable.
