backup options for ML350?

[elmurado]

Hi,
I'm in process of purchasing an ML350server and we will be mirroring 2xGB HDD for data and 2x36GB HDD for the OS.
This server we're buying comes with a HP72 DAT drive for which there are tapes which can go to 72GB compressed.

I want to be able to backup both data and OS but am not sure the best way to go about it with the current setup--especially as our data will no doubt hit 40-50Gb very soon.

Can I do this with the drive in question? Or will I need something with more capacity or a different method altogether?

Why not try a different approch to your back up, set up a schedule that backs up data every evening and do a system back up on a week end, This will only work if your data dose not change at the weekend.
Then you can use the latest OS backup and data backup to get back to a position where the least data has been lost.

Secondly your os data should not change very often the other idea is that you dont backup the OS at all and just backup the data, then in the event of server failure you can build to the OS and then restore the data....

Thirdly you can do a limited backup of the os eg dont backup thing like fonts,temp files, history ect ect and just back up the essential files and the registry.

What os are you using? does it rearly take all 36GB?


If you want to look into this further, this is a link to a good book although i have not read it it seem to get good reviews.

Forget the DAT72: I am yet to see better than 1.25:1 compression on any DAT drive: that's about 43GB on a DAT72. Typically compression is worse than that.

Obviously, the compression achieved depends on what you are storing. If your data is all Word files, then they compress very well and you may achieve 50GB. But most file formats are better compressed these days: you'll get virtually no compression from lossy graphic formats such as jpeg (which are already compressed), nor will a large Exchange store compress much.

I would recommend jumping up to an Ultrium 215: they have come down in cost dramatically this year and the blank media is a bargain! The Ultrium will back up all your data much faster too ensuring that it completes overnight - something a DAT72 may not achieve.
