Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Split a file into equal size chunks and archive to (e)mail account.

Split a file into equal size chunks and archive to (e)mail account.

This is just a little snippit to split a large file into smaller chunks (4mb in this example) and then send the chunks off to (e)mail for archival using mutt.

I usually encrypt the file before splitting it using openssl:

openssl des3 -salt -k <password> -in file.tgz -out file.tgz.des3

To restore, simply save attachments and rejoin them using:

cat file.tgz.* > output_name.tgz

and if encrypted, decrypt using:

openssl des3 -d -salt -k <password> -in file.tgz.des3 -out file.tgz

edit: (changed "g" to "e" for political correctness)

Alternatives

There is 1 alternative - vote for the best!

What others think

Awesome! What a great command for freeloaders who just want to take advantage of corporate generosity. Make sure when Google starts stopping people from doing this kind of thing that you complain loudly on your blog. Dirty corporations.

@ deltaray, not that it matters, but where I work, and use this backup method, we pay google to host our email for 3 domains. It's far from free and definitely not 'corporate generosity'.

Comment by tboulay 340 weeks ago

So you pay google a lot of money to host your e-mail but you resort to backup methods like this to save money? :-(

Comment by deltaray 332 weeks and 5 days ago

@deltaray .. A tape library, netbackup, offsite secure storage that's DR compliant + google hosting, .. or using the offsite, DR compliant, cloud space that we already pay for....
