Best practices for backups

Real Time Backup
I have been doing some research around solving the ever present issue of data backup for companies that have massive amounts of data and zero backup windows. I have my own ideas on this, but I was wondering the route others are taking. Any Ideas?, or any real world examples?. Is tape elimination on your radar? What about real-time backup of every write? Snapshots? How long does recovery take? In other words, how are you solving it?

Thanks. We'll let you know when a new response is added.

We have addressed this issue with real time replication to a secondary system that is backed up as a clone of the production system

Depending on you platform there are some good products out there to do this.

    this a deep issue where to start with the hw the sw-solutions; it also depends on the amount you have to backup why dont use both tapes (for some critical things) and raids, nas and things like this for all data ?

    Hi Chris, There are many takes on this, and to some extent it depends what you are backing up too. If you are talking about large scale database applications like ERP, then some form of replication is the best bet, and duplication of transaction replay logs too. Focus on tape is diminishing for sure, and if you can keep a disk backup available either as a snapshot, or as a mirrored (sync or asynch), offsite for DR purposes, then you can achieve the best of both worlds. There are a number of CDP products (Continuous Data Protection), out there too that offer point-in-time recovery to ensure RPO (Recovery Point objective) at or need to point-of failure. Guess at the end of the day its about justification, i.e.cost vs business requirement. Can't say what I would do without some more input ! Regards Dick Browne
