8 TB trust issues - Page 2

post #11 of 39
I have had hardly any of my HDD fail in their warranty period, and I have plenty. Really if you get some decent drives and take care that they do not get to hot, chances are they will surpass their warranty.

OTOH, I would never bet money on this. I therefore make sure I have multiple copies or backups of all. I have it pretty much automated or manually it take me 5 minutes to backup.my system drive for instanced.

To the point, if you don't pay attention to this you will loose data,

How is this hard to have a mirror HDD? Even better, with 3 drives you can get 2x single drive storage and have a backup in case one fail.
Anyway, I don't know any person that need more than a 1TB for storage. If you need more than that you simply need it for very specific reason.
It's pretty much common knowledge to back-up important stuff. I do it with CD drives, very convenient and it's there nearly forever. Plus it can't be accessed in case my computer is compromised. You can store lot of data on BR.

I don't know about you, but I have photos and home videos that amount to over a Terabyte. I don't think that is that uncommon nowadays.

One word will calm all worries: backup. I see it all the time with people loosing their data on their system because they don't have one. I don't care if you have a 20GB drive or 20TB drive. Backup is important. If you still don't get it, see my sig.

Let me further re-iterate what everyone else is saying. If you don't want to go through the hassle of a backup (no need for raid, just use another drive), then you are playing with fire and you deserve to get burned. If you have that much data, then you should expect to pay double to have a backup plan.

ALL hard drives WILL fail. Just a matter of time. I have seen it time and time again where I work. In the past month I have replaced at least 60-70 hard drives in customer's systems. Of those, about 30 of them had to go to advanced data recovery ($520-$2500) to get the data back off. IF the customers had spent 80-120 bucks on an external and setup a backup, then this issue would have been avoided.

I have a 40TB Synology server that is backed up to a second 40TB server once a week. Certain directors are backed up hourly. Only new or modified files get transfered after the first initial backup (which took 3 weeks because I cannot afford downtime).

I don't. I see no point in having new drives sitting on a shelf wasting warranty. Also, the prices of HDDs are slowly going down so a drive I buy today and not use for say, six, months will probably cost me less if I wait until I need it to buy it plus I will get to take advantage of the full warranty period. I can get a HDD replacement delivered in two or three days from the manufacturer if it's still under warranty. If not under warranty, I can still get a replacement in two or three days. In the meantime, I can substitute one of my backup drives for the dead one and still have one onsite backup, two offsite backups, and a cloud backup to fall back on if I manage to kill the backup drive while using it.

Yes it is. A backup in term of 1 drive fail, you lose nothing and can keep doing your operation normally. I am not a drive guru and don't need a thousand drives scattered around the world to preserve my data integrity. Don't be silly. I also back-up with external drive (archive) and BR disk.

@ OP if you have 4 x 2TB drives how do you use them?

Because if you use them for storing 8TB of stuff you should have at least 16TB of actual storage capacity so the data is at least backed up once.

If however you are already backing up the data and you use it as 2 lots of 4TB (one of the lots for back up) then you would have to replace them with 2 x 4TB drives not 1 x 8TB drive, that is if the aim of the upgrade was to reduce the number of actual drives you had in use.

Funny, I just got a new NAS with 8TB 4x 2TB Drives and actually configured them in RAID 0 just to see what the performance is like, plus I need 8TB Combined storage and I did not want to pay the large amounts of money for larger drives, say 1x8TB.

However I make continuous backups of all my data on External drives, so should the worst happen, I am fairly confident my Data is safe. if anything Data loss comes down to two things.

1. Configuration.
2. Human Factor.

You can have the best RAID/File Structure configuration in the world, but without an external backup you are risking your data. Secondly, Human Error plays a big part of it. Backup routines are hugely important. I tend to have an autobackup set and I also do a manual check to make sure that the backup has indeed been achieved, hell computers even if set to autopilot can still mess up and it would suck if you lose your data and rely on the fact that your PC/Server has correctly backed up. Monitor Monitor and Monitor again.
