how do huge company like youtube backup there data? if a problem like this happend in there
hehe - when it comes to storing lots of data - nobody uses 'domestic solutions'.
in my home i have around 80tb of data storage - and i'm not talking thumb drives and usb devices. raid 5 is a minimum nowadays for backups (i'm using raid 10) plus i have multiple jbod frames which i use for video editing and specific data storage.
i basically use the same level of data backup and protection that i use at work.
youtube etc sits on server farms - dynamic backups of backups of dynamic backups.
basically, you will probably never know if they have data loss, and when they do, the worst that the end user ever sees is 24-36 hours of downtime tops, which is the wait for the data to be rebuilt onto new drives.
basically, google raid, and read around it.
intresting information takomania, i didnt relly get what u mean about dynamic backups but googling it right now :)
So good news! Got my HDD back today! I've been making backups for the last 5-6 hours!
They said the HDD is fine, it was casing or something like that, don't know the right word in english.
Anyway I paid 40€!
i/o board/controller board would be the problem - it's the tiny little pcb board which connects the usb drive enclosure to the sata or ide connector on the front of the casing (the green circuit board in this pic)

- meaning you could have removed the drive from the case and put it into another enclosure or computer.
what brand is the drive? that's really really common with lacie branded drives...
I think it's Western Digital!
What's your electricity bill for that?Originally Posted by takomania

Not surprised really. In 90% of cases WD's HDD's get fucked up.

takomania I forgot to ask you, what software do you use for making backups?
@ yoco - for major backups that i need automated, i use symantec backup exec. another good one is acronis backup and recovery.
for small amounts of data, i just do manual backups, because i'm used to working that way and have done for many years.
@ lemongreentea - i'd love to know where you pulled that 90% figure from.
people seem to take their own personal experiences and those of friends when it comes to tales of various drive manufacturers churning out bad drives, but from what i've seen over the years, no one manufacturer is any worse than the other. western digital is often referred to as western disaster, seagate as shitgate etc etc etc.
yeah, hitatchi has turned out a bad batch of drives in the past, but so have others.
the only drives i warn people against buying are lacie branded removable storage, as their controller boards have been consistently bad for years - lacie are just style over substance (which is why apple love them i guess) and have a track record of failures in the media industries - i deal with a large number of companies that literally wont take digital media submissions on lacie branded discs, due to their failure rate. the hdd's themselves are fine - and are made by a range of manufacturers (hitachi, seagate, samsung to name a few) but the enclosure builds are awful and do are not up to the standard of even budget removeable drives - something that's shocking for a device that is made with mobility in mind.
oh, and my electricity is included in my rent (which is high anyhow!)
-and my kit is not all powered up 24/7!

I heard both of them, and also that Acronis has some issues sometimes(?!)
I have just over 100GB of music files, and I used Paragon Hard Disk Manager 11 for my backup!
One question. If I'll ever need to restore these files, do I need a recover cd or something?
Hey fellas! I have a question. If you HDD has bad blocks/sectors does that mean it's destined to be doomed or can complete format fix these issues?
usually, you just need somewhere to install the program, plus lots of drive space. (depending on what archive method you are using)
formatting wont really solve anything - using a tool fuch as hddregenerator can work wonders though (depending on the age of the drive and the number of bad sectors).

I already have this software. It's really good, but can be so sloooow! My 800Gb drive was scanning and repairing for almost 3 whole days!
well, you can't take shortcuts!
either that or buy a new drive
-edit-
also, i think you'll find that the software isn't slow - your drive is.
hdd technology has barely evolved since the 80's.

I'll probably buy a new 1TB drive next week, just for backups!
