If this is an individual end user requirement, you can create a PST (outlook data file) based on your details. You can't do a search in other backup machanisms.

With Outlook 2010, you can have unlimited PST sizes, though recommended is below 2GB.

ok thanks let me try that
so if i have to search in the backed up  pst, how can i do that ?
Murali ReddyExchange ExpertCommented:
PST or otherwise called as Outlook datafile, when created shows just like an extra mailbox space in outlook. But the disadvantage being, you can not access these emails if you are roaming (like you access your mailbox) as these are downloaded to the local/network space you saved that PST to.

You can just search these emails like you do it in your mailbox in outlook. there is no difference.

Hi ts84zs,

You can perform both archiving or exporting on the PST file to create backup. As I think, archiving in MS-Outlook is the best option to create backup as it creates another pst (archive PST) which don't put any impact on your current Outlook Data File.

Apart from it, through Exporting feature you can reduce the size of huge PST File.

Feel Free to respond back for further assitance!!

Thanks Clark, thats an option too. Even you have a choice to add only selected folders to archive and define condtions (age limits) to items to be archived.

In outlook 2010, got to the folder you want to archive-- Properties --select AutoArchive tab-- Select default or custom settings-- Note the auto archive PSt path and say OK.

However disadvantage is, it will move to archive pst all the items classfied by the set criteria, you may not be interested in. Yes, you can still drag and drop the items to the archive PST, which are not matching the criteria also.

If you want it simple and do not want auto archive to be enabled, create a outlook data file (PST) and start moving. Choice is yours.

Monitor the PST file size and ensure it is not crossing 2GB (recommended) and if so, recreate the PST(s).

Welcome Murali and Author for paying attention towards my suggestion. But I don’t think that in any aspect archiving can be a troublesome for a user who wants to create backup. Instead, moving emails can be trickier and even more time taken process if you go for an export option because each time you have to access it by importing them.
