We have an audit table in our ERP database that is 51 gb in size. I need to archive the data in this table and shrink it significantly. I tried selecting all the records to a file, but that took HOURS, filled up the drive space and brought the system to a crawl. I eventually ended up killing that process. But I need to know the best way to archive this data, and how to do that on a regular basis. Once it's down to a manageable size, I could write it to a table on another drive and truncate this one, or at least delete records older than 6 months or something.
I do have a full system backup that runs every night so I have everything backed up, but what I'd really like to do is get this single table onto a blue ray disk or just on another network drive because the odds of someone actually requesting any of this data is truthfully slim to none. But as soon as just truncate the table, someone will want to know something. We tried truncating in our development environment and it was really fast, and irreversible - LOL.
