RAID is a backup for a drive failing. Saying that it isn't a hard drive would be like saying a hard drive which keeps a copy of all your data is not a backup because a hurricane could take both of them out at once. Before planning your backup solution you should first figure out what you are trying to defend against.5 Jul 2021
What is a RAID storage system?
Redundant array of independent disks (RAID) is a storage technology that balances data protection, system performance, and storage space by determining how the storage system distributes data. Various RAID combinations provide different levels of protection against data loss, capacity, and speed.
Is RAID same as backup?
The main difference between RAID vs. backup is that, although backups help you recover from a data loss event, RAID exists as a tool for keeping data loss from happening in the first place.10 Nov 2020
What is RAID storage and do I need it?
Best answer: Redundant Array of Independent/Inexpensive Disks (RAID) is a technology that allows storing data across multiple hard drives. The purpose of RAID is to achieve data redundancy to reduce data loss and, in a lot of cases, improve performance. The best way to get in on the RAID action is with a NAS.9 May 2019
Which RAID is better for backup?
RAID 1 is the safest way to create an instant back-up of your files. There are two main sacrifices to the safety, though. The first one is cutting your disk space in half. If you have four 1TB drives in your RAID 1 set, the drive will show up as a 2TB drive.6 Feb 2018
Is RAID 5 good for backups?
RAID 5 the basics A RAID 5 array is great if you store a huge amount of data, because you just need one additional disk to provide redundancy. In our case at home we use a 4-bay QNAP storage for all of our personal data (mostly for pictures, movies, downloads, Time Machine backups).5 Aug 2015
Is RAID good for backups?
While RAID arrays can provide enhanced data protection, their extra disks should not be considered as backups. If your main drive is a RAID array, you still need to back it up. If you have, say, 12 TB storage on a RAID array, you'll want to back it up to another device.10 Feb 2021
Can RAID 1 be used as backup?
One very important thing to note, RAID 1 is not a backup in and of itself. Although RAID writes data to two disks simultaneously, it is not a backup. If your operating system or software, rather than the hard disk, corrupts your data, this corrupted data is sent to both disks and simultaneously corrupts both drives.6 Feb 2018
Does RAID 1 count as backup?
RAID is not a backup mechanism; it's a redundancy mechanism, and it does a completely different job one protects against disk failures, the other protects individual files.8 Jul 2019
What is difference between RAID drives and backup solution?
The basic purpose of RAID is to provide redundancy, if one disk fails, the other drives essentially take over until the failed drive is replaced. Backups on the other hand protect against data corruption and loss, but don't provide true redundancy.13 Jul 2009
Can RAID be considered as backup?
Is RAID a backup? While RAID arrays can provide enhanced data protection, their extra disks should not be considered as backups. If your main drive is a RAID array, you still need to back it up.10 Feb 2021
