RAID.looking For Total Redundancy
Without access to this information, the user is left unaware of classic warning signs of impending disk failure, like reallocated sector count or unusually high temperature. A backup consist in a policy and strategy to save (backup) your data in the best adapter manner for your use.

If you aren't using something that is known to use synchronous writes like NFS or databases, chances are your SLOG will not help performance. monitoring utility “smartctl”. Other Issues to Watch For There are a couple of common issues with Active Directory that can cause problems. Speed – they are fast.

RAID10 - Best performance for Read and Write, but lowest useable space (50%) NB useable space is "Total disk space" - "redundancy overhead" Link Nation Ali June 11, 2014, 5:26 am Guess what? In a four drive configuration, two mirrored drives hold half of the striped data and another two mirror the other half of the data. However, it is NOT a whole backup solution.
Minimum 2 disks. If for example i had a 10 disk raid 10 setup, if i pulled 1 of the mirrorsets (2 disks) would this result in data loss? It's for pros and crazies handling massive files, like HD video editing. Raid 50 For months I spent time looking up solutions (softwares and hardwares) and they all sell how good they are with backing up and how easy it is restoring, which to my

Raid 5 Explained The problem with considering a RAID as your backup is that it doesn’t help you with file deletion, corruption by applications, operating system or viruses. No I have 4 ZFS NAS backup boxes i've built and they work well. However on several occasions it has happened that all of a sudden, time machine completely erases itself and starts over from scratch.
So you really could buy several if needed or smaller drives if not including the Passports you are using which are just fine or the smaller Seagate backup drives. Raid 5 Vs Raid 1 Dong Ngo/CNET Desktop storage devices are generally based on the 3.5-inch (desktop) internal drive. If either drive fails, you can continue working with the other until you can replace the bad one. Last thoughts on redundancy: No matter what type of redundancy RAID you use, remember that it's just like insurance, something you need to have just in case, and hope that you

Raid 6 While we have created a best practices for FreeNAS, we also decided to take a look at what you don't want to do; things that will leave you hurting either immediately
In reality, your data is likely hosted by multiple servers in multiple data centers around the world. http://robotadv.com/raid-5/raid-5-help.html The option to hot-replace a drive should be used only when absolutely necessary and not viewed as a "fun" or "cool" feature. I will appreciate your answer as I plan to purchase a Western Digital "My Book Thunderbolt Duo 4TB Dual-Drive with RAID" to replace an older 2TB "Iomega Companion for Mac' that Raid 5 is not for speed, its actually slow on rebuilds.

Link Gerald September 30, 2014, 1:59 am @Rainbow - Of course! Good performance ( as blocks are striped ). Next a Raid backup unit and as large or as small as you need are available and Synology has been extremely solid from low end to high end. http://robotadv.com/raid-5/raid-5-help-please.html Thanks in advance.
Reply Pete Marovich says: March 19, 2016 at 1:12 pm Seems reasonable to me. Best Raid Configuration Once it's set up, it will run by itself and you don't have to do anything else. Their backups are in a safe deposit box.
It also doesn't require you to purchase extra equipment, or use more energy than you already do.
Excellent performance ( as blocks are striped ). e.g. How to undelete a file or multiple files. Raid 01 FreeNAS provides this via the GUI and e-mail.

If you need more disk space you cannot simply add another drive to the array, you would need to start from scratch, rebuilding/reformatting the array. weblink Online backup (also known as cloud backup) An online backup service allows you to store your data at an off-site location by uploading it via the Internet to a remote computer
The “one big disk” that hardware RAID cards provide limits some of ZFS’s advantages, and the read and write caches found on many hardware RAID cards are how risk gets introduced. If you can't use raid for backups then I would suggest keeping multiple backups on cheap usb drives. For most home use, network backup is also overkill. Of course since the system disk has nothing on it but the system and the applications, I can also do a pretty fast recover from TIME MACHINE of that drive if
