I changed TAPESIZE from 70 Gb to 65 Gb, and the problem was solved.
Thanks.

I liked your answer. I'll try to do this. On monday I'll informe you
if the problem was solved. Thank you.
------------------------
The $INFORMIXDIR/etc/$ONCONFIG TAPESIZE parameter is most likely set to
high. Remember, as the data becomes more compressed within dbspaces (thru
attrition, reorgs, etc) the tape drive compression is lowered. Example,
our DLT7000 tape drive using 35/70 gb tapes were able to compress up to 70
gb without having ontape abort, but the TAPESIZE parameter had to be
changed to 65gb recently.
Sounds like you are reaching the peak capacity of the tape, so lowering the
TAPESIZE value should do the trick.

Help me
My level 0 backup is aborting all day in 90 percent(in the last
tape).
Information:
Database size: 400 gb
Number of tapes: 6(70 gb each tape)
SAP version 46C SP39
Informix version: 7.31FC6X2
Unix version: Digital UNIX V4.0F (Rev. 1229)
History:
My level 0 backup was normal.
For 5 days it aborted in 90 percent, then I changed the tape
drive.
I changed the tape drive, then the backup finished.
But in the next day it aborted again in 90 percent.
I changed the last tape.
The backup aborted again in 90 percent.
