Re: Verifying tape backup
User asked how to verify vdump backup tapes in Informix SE 7.32 on Tru64 Unix without restoring them. Art Kagel confirmed there's no way to verify without restoring, and recommended using vrestore with parameters (specifically vrestore -t -f "tape device name") to verify tape integrity.

Hi Art, So do you mean that I have to use the vrestore command with some parms to verify if the tape is backed up OK? Thanks, Long N.

Hi Art. To be more specific: vrestore -t -f "tape device name" is sufficient? (I haven't used it for sometime so not 100% confident). Long N.
