“For the wise man looks into space and he knows there is no limited dimensions.” — Lao Tzu
I’ve always suspected that pornography has a history with mankind but I never guessed that the founder of Taoism had already been downloading enough to foresee virtually limitless data capacity needs. History repeated itself as I logged in yesterday just to notice that the free space on my hard disk was about 400 MB. Panic time, and the only efficient solution I could work out was to buy a Western Digital 320 GB portable hard drive.
Now, these days, buying any digital storage medium which has its capacity advertised in GBs is subject to the 7.2% deficit rule (I just conjured this name so I can’t be held responsible if it doesn’t occupy an entry in Wikipedia yet). The rule is simple: For every digital storage that you buy, you won’t ever see 7.2% of the GBs quoted on the product. Which means, if you buy a 250 GB hard drive, you’ll only be able to use 232 GB. For my 320 GB buy, I lose
320 x 7.2% = 23.04 and end up with 296.96 GB. Unless you’re prepared to tackle the difference between powers of 2 and 10, don’t even bother questioning the origins of this rule.
So, the passport drive came bundled with some software for synchronization and encryption. Did I bother? No. I reformatted it straight away as an Ext3 partition. After that, TrueCrypt and rsync were more than enough to cater for all my needs without any hassle. For the curious, here’s the command that I used to synchronize my home directory:
rsync -r -t -p -o -g -v --progress --delete --exclude=".*" /home/krkhan/ /media/Inspirated/Home/
This would exclude all hidden directories, and synchonize the
/media/Inspirated/Home to mirror the exact state of
/home/krkhan. The fun part, for those unfamiliar with
rsync, is that if I synchronize, let’s say, fortnightly; only the data newer since last backup is copied.
I hope it would be least a couple of years before I get to quote Lao Tzu again.Tags: Backup, Data, Hard drive, Portable, rsync, Software, Storage, Synchronization, Technology, TrueCrypt, Western Digital
