I have absolute confidence in the Informix archive. I too back up using
ontape and have restored (to a test machine) on numerous occasions with no
problems.
Do you have some very old data in your database? It could be you are
encountering the 'archive very old page' bug which slows the archive while
it updates the timestamp on very old pages. Once they have been updated (and
if there is no other activity on the system) they will not need to be
updated if you archive again immediately after.
You do not say what the normal length of time of an archive is, or is this
the first archive for some days (weeks, months)?
A bit more information.

-> Hi all,
->
-> I have some doubt on the informix backup. I'm using
-> ontape command to perform level 0 backup on my Test
-> database (7.31.UC2). The first level 0 backup took
-> around 2 hours to complete and the second time of
-> level 0 backup only took ~45min. The second time of
-> the backup begin right after the first backup
-> completed. There's no other transactions running on
-> the database during the backup. Which means that the
-> data for both archive is exactly identical. My
-> question is why second backup take shorter duration to
-> complete compare to the first backup
->
-> Does any one of us know where can i obtain the
-> documentation to describe how informix archive works?
->
-> TIA,
-> miyaki
