I think what he meant by "to the hour" was not to the point of failure but to any time within any day of the week.
I have seen a number of backup programs (Legato for example) where you can pick a day and time to which you want to restore. If you were doing full+incremental or full+differential --- it just restores full and then only enough transaction logs to get to the required point in time. -----Original Message----- From: Woodruff, Michael [mailto:[EMAIL PROTECTED] Sent: Thursday, December 04, 2003 11:50 AM To: Exchange Discussions Subject: RE: Backup rituals With a full all you need is one tape and the transaction logs and you will be able to restore to the point of failure.

The reason being is that incremental do not commit and flush the transaction logs. Only a full backup will do that. In addition, you will want to familiarize yourself with this: http://www.microsoft.com/exchange/techinfo/administration/55/BackupResto re.a sp Unless you use a different version of Exchange in which case you will what to find the appropriate DR whitepaper. You should setup a DR server to test these processes on. By server I mean any spare PC that has enough disk space. Just to learn it. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Eric Fretz Sent: Wednesday, December 03, 2003 7:27 AM To: Exchange Discussions Subject: Backup rituals What backup rituals do you guys use on your Exchange sites? I've looked through the FAQs and read most of the relevant Microsoft Qxxx articles on Exchange administration, but I haven't found "the" way to do good backups. My first blush is to backup the entire databases + logs once a week and then backup the incremental changes to the logs daily. All suggestions, snide remarks and pithy one-liners are welcome...
