The Graveyard - Products No Longer Supported => D-Link Storage => DNS-323 => Topic started by: MonsterAcer on March 04, 2010, 09:51:31 PM

I bought this a week ago and I am transferring all my data (home business and personal family stuffs) to DNS-323 (two separate drive of 1 TB). I read some of postings and worried about losing my data in case this is not accessible for some reasons.
Is it risky to have dns 323 as my final back up? Are you guys advising to have another back up,,external hard drive, a descent one such as WD, SEGATE, etc?

IMO it is no worse/better than any other HDD-based solution.
Always make multiple copies of data in any backup solution. Ideally, have a copy of anything critical on a non-erasable media (DVD for example).
The DNS323 is perfectly acceptable as a PART of a backup solution.

Also,....
Keep in mind that many of the issues discussed here are not DNS-323 related, they are computer setup issues, firewall, router, etc. Many are due to users not taking the time to understand / configure the units properly, using 3rd party software, etc.
Some are legitimate issues, some are lack of information issues.
I've had mine for a few months now, use only the basic NAS functions (mapped drive configured as Raid 1) and have had 0 problems, using it daily from multiple devices / computers. There are thousands of customers (I assume) that never post here that have no issues.

Thanks...

RAID of any level is NOT backup. Having one copy of your data in any format is a huge risk.
Remember: Data you don't have at least two copies of is data you don't care about.

What risk are you worried about?
Having a DNS-323 in RAID 1 (redundant disk) mode gives you excellent protection against mechanical or electrical failure of either disk DUE TO RANDOM EVENTS. The chance is truly miniscule that one disk would fail, and the second follow would before you could obtain and install a replacement disk. Not a zero chance, but definitely you could claim some geek sympathy.
The chances are much higher that both disks and/or the DNS itself will fail if the unit falls off a shelf, your house burns down or is flooded, your power line is struck by lightning, or if there is a software error that nobody knows about (yet).
The chance is essentially 100% that you will lose data if you delete it inadvertently.
If you have data that you really, truly can't afford to lose, then you can't afford not to have one or more off-site backup copies, preferably on write-once media. Only you can make the call as to what qualifies.
Personally, I run my PC with a RAID-0 pair of disks, make frequent backups of critical data to my DNS-323 with a pair running in RAID-1, and sleep like a baby.
