It seems to me that a lot of folks in the security industry these days are overlooking some of the basic, basics of computer security. Good, reliable backups are just about step 1 or 2, next to good physical security. If a box is ever compromised, how would you ever recover without a backup? If you suspect tampering, and you had no previous "state" of files recorded in a backup, how would you prove your suspicions? Backups are very much a part of security, and I fear becoming more and more overlooked.
Just my 2 cents. Toby Owen -----Original Message----- From: Jeff Giuliano [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 20, 2001 4:38 PM To: [EMAIL PROTECTED] Subject: Re: hOt or cold back up? Hot and cold backups refer to backing up a database. A hot backup is a backup of the database while the database is up and running. You backup software needs to understand the internals of your database in order to perform it correctly. Hot backups often end up being invalid due to the nature of databases. A cold backup is a backup of the database after the database has been shutdown. This requires downtime of your database. A new method of database backups is to mirror the database, then "break" the mirror, then backup the mirror and then resynchronize the mirror with the active database. No downtime, no database integrity issues. I recommend O'Reilly's "Unix Backup & Recovery" by Curtis Preston if you want to know the details. I'm not sure what that has to do with security though. Hope that helps. -Jeff > -----Original Message----- > From: Rodrigo Ramos [mailto:[EMAIL PROTECTED]] > Sent: Monday, December 17, 2001 4:32 PM > To: [EMAIL PROTECTED] > Subject: hOt or cold back up? > > Hi, > > Can anyone tell me the difference between hot site back up and cold > site back up? > > Thank you very much? > Best regards, > Rodrigo Ramos
