Storage Space Management:

DB space is costly than anything in the world . You never get approval of more space in one shot and SharePoint need more space. You need to manage your own space. The question is how to manage it? Be proactive, review SharePoint site collection and the available reports from the top level site in the site collection. Take a snapshot of this, and contact with site collection administrator and aware him, or her about the space consumed by document library or list and the by the entire sub sites. Ask administrator to convey the message through the form of eCampaign to the sub site administrators or to those people who are managing the document library/list. Time is needed to shrink the data from SharePoint.

Advice them to review the versioning of the files, better to keep with last three versions of file in document library. Find out those sites which are not edited for last one year, and ask the site administrator or business owner of those sites, if those are still required.
Archive is a good mechanism to save SharePoint db space at the cost of primary hard disk space. There are few third party archiving software available in the market like DocAve, Idera. You could use any of those to archive your SharePoint data. It will basically let you retain back your db space at a cost of 1:1 consuming less costly harddisk space. In other words the data save in database will be migrate top hard disk. So, if there are around 250 doc/excel/powerpoint files at SharePoint database with average size of 4 mb, then after archiving, the total space you can save or retain in the database will be around 1 GB! However it will price you to spend 1 GB of hard disk space to save that data over there.

Another way to take SharePoint data backup is using STSADM command line tool. Using this tool, you can also take the backup of entire site collection or the team site and latter purge the site for retain the db space.

Policies:

Policies need to be implemented to keep running a stable and organized SharePoint farm.
Start from the root – your first action item would be implement policies when a new team site will be create. What for this space is required and the expected growth over the year. Asked those questionnaires first before create the site. Always implement quota template on individual site. It will help you to keep the growth of the site collection within a limited size. After all there is no harm to increase the quota template latter on.

Every SharePoint sites need to be validated on every six months. Those sites which are not activated last six months need to be quick review. Asked the associated site administrator of those sites, and if it is no more required, shut down the site.

Project close out policies – Once a project will be complete in the organization, and wrap up, it need to be mandate to keep inform firm administrator to give them back their SharePoint site. This way you can control the garbage collection in SharePoint.
 
Effective campaign management – Delegate the task to site/sub site administrators to aware site user to keep with less versioning, and clean up the site as quarterly activities. Check whether the site is still valid, or could be return back.

Identify those files which need to be place at SharePoint, but do not required edit on monthly basis. Compress those files in SharePoint. It will save a lot of space for you.
There would be more to implement. Justify your explanation to business and implement the policies to keep running a healthy SharePoint application. Good luck!
