any help is appreciated, I have a SQL 2012 enterprise server, and I'm using Commvault as my backups. So commvault can restore a .bak file to my server, but it cannot use sql compression on the file apparently. So what would be a 150GB .bak backup file is now 600GB. I have to manually upload these files to an auditing firm on an sftp server and the transfer times are now huge.
Is there a way to use something in sql to compress this already existing .bak file down? sql command line or something? any help is appreciated, thanks!

Windows has built-in ability to compress files. 7-z or others may have command line ability too.

You could stop using Comm Vault. Also, are you 100% certain it cannot use compressed backups?

Ok, thanks, is there a way to use windows (2012r2) to do it with a command-line? Just trying to automate it without having to install extra software on a production server.

And i did verify that with commvault tech support. Commvault is working well and is our enterprise backup solution and does all our backups and restores, this is just a one off restore i need to take off site

Thanks!

Sorry, but Commvault cannot be said to be working well if it cannot use SQL Server backup compression.

I have no idea if you can do a command line zip of a file in Windows 2012 R2. But I am certain a little Binoogling can find the way for you. Powershell may well be involved.

Send a tape via FedEx. It will get there almost as quick (maybe quicker) and cost you a whole lot less. Either that or do a "Copy Only" backup with compression so as to not upset the backup chain on CommVault.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

ok, thanks. And Commvault does work well, it's an enterprise solution that does back up and restores, replication, log shipping, deduplication, disaster recovery, etc., all perfectly across our environment. This is just a scenario outside the scope of what it can do since the backup has to go outside our environment.
