What is the best backup solution?
 

I am looking for the best backup solution. What is it?

Internal raid?
External raid?

I have had standard external HD's but I have been having some issues with their qulity and saftey.

So what is the best solution?

TIA :thumbsup

maxtor one button external harddrives work awesome

I've had my maxter externel drive crash twice on me...

for my personal perojects, I use:

Best: offsite backup (webair coached me through this)

Good & cheap: Buffalo Terastation

I have had nothing but problems out of Maxtor.

For webservers, having warmswap standby units in another facility is the best. If you dont have raid on your boxes, your gambling with your livlihood every day.

For home computers, having a simple backup HDD is fine. I replace my HDDs every two years on the home systems whether needed or not. Matter of policy after I spent a bunch of money to have a drive recovered professionally. New HDDs are cheap (esp. after Best Buy rebates) compared to pro data recovery.

"Best backup solution"

It may not be the cheapest, but having your backup offsite is ideal.

redundant in house backups on removable HD's and at least one copy of the same HD's offsite at a friend's house.

for home PC theres:
Windows XP built in backup program. inside system tool. I just add 1 huge hard drive inside.

for unix servers: theres scheduled mysql hotcopy then rsync to another server.

veritas storage foundation beeitch

That is what I am replacing

Thanks that terastation looks good for the $$$

Can you elaborate on the offsite backup

Thanks

are you talking about server or your PC backup? for a server backup just use a second drive on or off that server. same would be for your own PC backup actually. just remember to keep 2 or more copies of data on 'separate' physical devices, that's the main idea of any backup.

with all of you guys just copying your server to a hard drive, what if you got hacked? What if the hack was last week and you just now noticed? What if your attached backup hd is corrupted too? if your not keeping some sort of offline daily/weekly/monthly archives its a bad idea.

I prefer to use SDLT tapes with a robotic changer. Vertias BackupExec works great. it aint cheap but then again it's worth it. :2 cents:

Call me paranoid, but my personal preference is a raid 5 array in the server itself, and then I back up any changes to that using tump over ssh to an simple two driver raid mirror I have here at the office. I then have one of the drives on a removable sled and take it home with me each nite....

What is the best Raid to set up?

There are number of different RAID levels:

Level 0 -- Striped Disk Array without Fault Tolerance: Provides data striping (spreading out blocks of each file across multiple disk drives) but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost.
Level 1 -- Mirroring and Duplexing: Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.
Level 2 -- Error-Correcting Coding: Not a typical implementation and rarely used, Level 2 stripes data at the bit level rather than the block level.
Level 3 -- Bit-Interleaved Parity: Provides byte-level striping with a dedicated parity disk. Level 3, which cannot service simultaneous multiple requests, also is rarely used.
Level 4 -- Dedicated Parity Drive: A commonly used implementation of RAID, Level 4 provides block-level striping (like Level 0) with a parity disk. If a data disk fails, the parity data is used to create a replacement disk. A disadvantage to Level 4 is that the parity disk can create write bottlenecks.
Level 5 -- Block Interleaved Distributed Parity: Provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance. Level 5 is one of the most popular implementations of RAID.
Level 6 -- Independent Data Disks with Double Parity: Provides block-level striping with parity data distributed across all disks.
Level 0+1 ? A Mirror of Stripes: Not one of the original RAID levels, two RAID 0 stripes are created, and a RAID 1 mirror is created over them. Used for both replicating and sharing data among disks.
Level 10 ? A Stripe of Mirrors: Not one of the original RAID levels, multiple RAID 1 mirrors are created, and a RAID 0 stripe is created over these.
Level 7: A trademark of Storage Computer Corporation that adds caching to Levels 3 or 4.
RAID S: EMC Corporation's proprietary striped parity RAID system used in its Symmetrix storage systems.

I am also looking at these models. What in your opinions are the best to go with for both performance and fault tolerance?

Thanks again guys

offsite data backup would probably be the best solution it's a lot cheaper and more reliable in most cases....

been using these guys for a while now great piece of software and there servers are on point... you create the encryption key so only you can access the data not even they can access your files...

Looks good I may do that as well as one of the appliances I posted above.

I am leaning towards the anthology model but the buffalo looks good at half the price.

I went with the Anthology Solutions model.

Will let you know how it performs when it gets here.

i want band.com =((

Send me another e-mail.

I may have a new option that works for both of us in terms of $$$
