Why should you? Again we are talking Unix here. Use sth. like
# tar ... | dd of=/dev/rmt0 obs=20
It would be just a matter of combination to write directly onto a tape.
You might find the following information useful:
AIX Backup tar CPIO Restore
That does not use compression.
What I am trying to achieve is backing up to tape any folders containing backup files, using compression, not using the current folder as temporary storage (no space for it). All this on an AIX 4.2 who's TAR does not have any compression on it and where I only have 'compress' as compression tool (althougth I said we had gzip, it is not on all our server and I am almost on a deadlock situation when talking to my team lead about copying it to all our servers because he says the license is only on one server !!!)
We have 10 backup disk folders (totalling anywhere between 60-90Gb) on 5 servers (2 DB per servers), each with one single tape drive. The current procedure to do this takes almost 12 hours to do !!!!!!!!! I want to reduce them all to less then 8 hours by using compression (just compression a 1.9Gb file on disk takes 25 min !).
