There's not much competition when it comes to compression utilities: 7-Zip is king of the hill. If you have it installed, but haven't updated in a while, grab version 18.05 right now. The latest official release, it contains a bunch of speed improvements so archiving is that much snappier.

Once you've found a file archiver you're comfortable with, it's hard to switch to something else. First WinZip, then WinRAR and now most people are happy with 7-Zip. However, if you're willing to try something new, Bandizip is worth the effort.

You probably know about the Internet Archive's Wayback Machine, which lets you see how a given web page looked at different points in the past. The algorithm used to archive pages, however, is somewhat random. If there's a specific page you want to capture for posterity, you can submit it yourself.

With the amount of data we store increasing at an exponential rate, many of us turn to archiving technologies as a way of protecting the most important information. I have a pile of CDs and DVDs with photos on them but none of my computers have an optical drive. NASA found itself in the same situation.

Disk is now the predominant backup medium, but tape still plays an important role. What do you do if you've migrated your main backup strategy to disk but still need to access older archives that are stored on tape formats? Rather than paying to maintain little-used tape readers and the backup software that goes with them, one solution is to put a company on contract to perform that work.

Windows only: System utility Deskcretary cleans up your desktop folder with scheduled or manual scans, archiving and compressing files into a separate folder automatically.

As with the iPhone, the just-released Palm Pre can sync up with a Gmail account, but doesn't offer a native Archive button. With a familiar settings work-around, your Pre can start thinking like a real Gmail client.

Windows/Mac/Linux (All platforms): Having an automated, secure, off-site backup solution is a great idea, but for many folks, burning their data and system files to CD and DVD is just more manageable. Free indexing app Virtual Volumes View (VVV) helps you keep track of exactly which file is located on which of those numbered DVDs. Once you've let VVV take a look at each of your discs, it can show you them in a physical view (each disc and its contents), a virtual view (one giant file system), or let you simply search through files, including MP3 metadata, to find that certain folder or file you need to restore. The app helps you make sense of large folders you have to break up into multiple discs, and is smart enough to properly index a newly-burned, updated disc it already is tracking. Virtual Volumes View is a free download for Windows, Mac, and Linux systems; Linux users, hit the Linux.com link if you need help installing. Virtual Volumes View

Productivity writer and Inbox Zero advocate Merlin Mann shares some of his recent updates to his talk about email-wrangling, including a bit of advanced common sense about why stashing away your emails isn't productive. Acting on them, and then killing 'em off, Mann says, is where you want to be: The idea here is that you probably don't have a place in your home or office where you store the shells from every peanut you ever ate. If you did, you'd definitely want to organise them by the year in which you ate them, perhaps keeping separate jars per-month or per-location where you ate the nut. You know. For posterity.
