RAID is never the replacement of Backup
Thursday, June 25th, 2009I learned a hard lesson, and is now paying off.
I can’t believe what I typed before my eye, I just did “rm -fr public_html”. A Ctrl-C stopped bleeding, but it doesn’t help from losing 1GB+ of files.
RAID won’t help in this case, but I have backup.

you’re lucky to have had a back up. Personally, I always make back ups before I make any changes.

I agree. Never rely on RAID or your server’s backup. Make sure to have a decentralized/independent backup. I learned this the hard way

I’m still pretty amazed that people don’t backup their data. I’d say of my clients, less than 1% have a backup that has happened in the last 30 days. And I’m probably even being generous with that.
Of course then you get the real freaks like a client of mine this morning that wanted me to bring a degausser to completely erase his hard drive. I went so far as to show him a sector by sector look to show him the drive was completely wiped clean. He was an odd one…. child porn anyone?

RAID is not a replacement for backup. Some learned it the hard way. Remember this or do you also want to learn it their way, too?

You entered _that_ command. Were you very tired, or possessed, at the time? Yikes.

As our concept, RAID is used for system backup, just for the harddisk.
Like my practice, if I setup a server, I also do incremental backup daily, and full backup weekly… …
I told my client, RAID is for your computer that has HDD error, you still work, but don’t believe that can save your data … … That just increase the problem if you really lost data… … XDDD

“RAID won’t help in this case, but I have backup.”
I just learned what a back-up is last week. This week I bought myself an external hard drive just in case my whole system crashes on me. RAID is a good security blanket but a back-up is a surefire way to avoid heartbreak.

That’s good advice. By the way, what kind of RAID did you use? Did you use RAID 1?
August 9th, 2009 at 22:15
Like my practice, I would like to use RAID 1 on AD Server, and for the File Storage, I would like to use RAID 5, for the Hardware backup and Performance………….
For Exchange, cause the memory is important than the HDD Read & Write, I will use on RAID 1, then for the backup will point into RAID 5 Storage Server.
Cause RAID 5 Controller if have any problem, will crash the system. However, Mail Server I cannot let it down a long time.

“RAID won’t help in this case, but I have backup.”
That is an important rule to remember because believe or not, many people still forget to create backups, and that includes me.

This is definitely true. It’s always best to have a backup for your files. You’ll never know what may happen, what with all the bugs, viruses, and malware that continue to infect various computers worldwide.

Having a backup is always a must especially if you process plenty of important files through your PC. USBs are handy backup tools that can save lots of data.

Nothing beats the good ol’ practice of backing up your files. You can’t compromise losing all your data,

“RAID won’t help in this case, but I have backup.”
It is always best to be safe and sorry so take time to create back ups especially for important files.

Nothing can replace a back-up. This is why you should not forget to have one no matter what happens.

It’s a sad thing that you learned your lesson the difficult way. But at least you learned from your mistakes.

Its always essential to keep a backup of the data. You never know how and when you lose it so better be on a safer side.
