How To... Backup Large DB...

hardware configuration:



2 node cluster, active-passive

+

for backup: direct attach tape library (dell powervault 132T with 2 tape drive's) on 1 node. Tape type is LTO (100Gb, and with compression 200Gb). Last time one filegroupe backup with errors:



Job 'BackupFG_index_ToTape1' : Step 1, 'step' : Began Executing 2007-07-02 Job 'EscortBackupFG_index_ToTape1' : Step 1, 'step' : Began Executing 2007-07-16 01:00:01

10 percent backed up. [SQLSTATE 01000]
20 percent backed up. [SQLSTATE 01000]
30 percent backed up. [SQLSTATE 01000]
40 percent backed up. [SQLSTATE 01000]
50 percent backed up. [SQLSTATE 01000]
60 percent backed up. [SQLSTATE 01000]
70 percent backed up. [SQLSTATE 01000]
Msg 4028, Sev 16: End of tape has been reached. Remove tape '\. ape1' and mount next tape for BACKUP DATABASE...FILE=<name> of database 'pakdb'. [SQLSTATE 42000]


i'am use native SQL Server backup, t-sql script:



BACKUP DATABASE pakdb
FILE = 'pakdb_index',
FILEGROUP = 'db_index'
TO TAPE = '\. ape1' WITH INIT, FORMAT, STATS, NOUNLOAD


i have 2 way's for solving this problem:

1) using any software (veritas as axample)

2) breack large filegroupe on any small filegroups - don't good think



Question:

How you solve this problems. Use veritas (example) - it problem too, if server full dead and veritas repository too - how i'm can restore information from my types (it's my ideas).
