You cannot use v9 with a 'clear conscience' as it is EOL and it has no support. I hope your 'supported' clients are aware.
V10 can be used, and is used, by many because it is the supported version, unlike v9. It has 'proper' backup solutions. But maybe not the one you want.
You have been aware of this issue for a long time but I haven't seen an offer of help so far.
I'm not a programner either. I just rolled up my sleeves and started to hack. You could do the same.
Please all stop asking when it will be done.
I'll do what I can, when I can, around my normal day job.
If you want it done faster the code is in CVS. Please start work.
