Re: rsync] Live DB backups with rsync?

I was just talking to livevault.com they (only on win boxes) say they can grab changes from a client's live DB sync them remotely. It sounded like BS to me, but I'm neither a DB guy or sync'ing expert. I've done with unix DB, DB4, and MySQL backends [not of choice, but sometimes, there's no other way, as when a hard drive is dying, and you _know_ you will never be able to power it on again ...] -- it works this way -- 1. Rsync the directory tree holding the database 2. Re-run the command 3. Keep re-running it, and eventually, you'll get an essentially immediate return with no content being moved. ... at this point stop. You hit a time when the database was largely quiescent, and so was unchanged -- -- there will be some open locks and and open transactons will be lost -- but no worse than an unplanned reboot due to a power loss. In a production environment, it seems to me that better ways usually exist. -- Russ Herrold -- To unsubscribe or change options: http://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.tuxedo.org/~esr/faqs/smart-questions.html

Since new bug reports are relatively rare, but problems and misunderstandings seem to occur repeatedly I think this would be the most useful way to get all the information in one place. So who's interested in working on that? Really a better FAQ editor process seems more useful. Isn't this the purpose of a CVS and commit privileges -- set up one or more trusted editors with rights, and delegate that aspect. For the last year, I have acted as editor on the RPM website; there is also an open editorial mailing list, and provided content (dreadfully little) gets slotted in. I monitor all the mailing lists in the area (five primary ones) and watch for common questions or misunderstandings which are well answered end up summarized and on the site. I particularly look for the postings by the lead maintainer and a few others for the 'nuggets' -- the answers float by and may be picked out of the stream and tossed up on the riverbank of a FAQ -- Russ Herrold -- To unsubscribe or change options: http://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.tuxedo.org/~esr/faqs/smart-questions.html
