db backup script needed

Hello guys, I need a script that backs up the database running under cron. I just wrote an internal (quite important, but not fast growing) database and I HAVE TO release it by next Monday. Something is going quite strange in it on updates, it often updates other fields that it shouldn't touch... some staff amazingly is getting inserted where I don't tell him to... some fields are even being deleted... you can imagine this nightmare... in other words I haven't had time enough to test it and in order to release it I want to back it up the working database on a daily basis. So I can still hack with it while it is being operated... oopps, again wrote too long ... anyway, is there any script like that (fast and dirty is ok) to run on MySQL, PHP4.0.2 ? P.S: I have a quite good idea on how to write it, but NO TIME..... Thanks Maxim Maletsky - maxim@j-door.com <mailto:maxim@j-door.com> Webmaster, J-Door.com / J@pan Inc. LINC Media, Inc.
