In my home network.
2 pc's and 1 tablet PC
All ran through router (wired and wireless)
Tablet does not need a redundant back-up

Main PC stores video and images
other PC stores images.

I lost 2 hardrives in 2 days!!!

Main PC has SCSI 160 card with 4 drives and 1 80gig IDE for backup
Secondary PC has 3 IDE drives, no back-up.

I want something that will keep 2 copies at the same time.
Can I convert my SCSI machine to something like RAID??

Or should I buy dedicated SATA drives with a raid controller and start
from scratch??

This would not be a major problem if I kept up with my DVD back-ups...
so I need something automatic and redundant.

thanks!

My primary concern for backup (redundancy) is harddrive failure.

I keep my OS (winXP) and progam files and data on 3 separate drives.
I need a redundant real time back-up for my data drives

I figure my apps and WinXP are safe on single SCSI drives. and if they
crash I can always reinstall from CD... (which isn't always a bad
thing)

How do I upgrade/replace my IDE data drives.
2 PC's with their own data.
I would like redundant data swapped between each PC.
My photos I work with on PC 1 are backed up on PC2
My video's I work with on PC 2 are backed up on PC1

SCSI SATA IDE RAID?? What do I need?

I have no back-up...
unless I start buring to DVD...

I could care less about an day/hour of work.
It is the total drive

Could I make 1 PC into a sort of Data server... that would store and
back it all up. (my wife could still use it to surf the web)

And then my main PC to do all the work???
 
Archived from groups: comp.sys.ibm.pc.hardware.storage,comp.periphs.scsi (More info?)

The data drives that failed were from each PC.
These were both older (cheap) large capcity drives.
They were both IDE

My SCSI drives are older, and have never had problems.
The SCSI drives store WinXP and program files (one drive for each)
Large SCSI drives are expensive, so I chose IDE for storage.
SCIS is faster, so I have 15k rpm (smaller drives) for WinXP and
program files.

Your replies are great... but there are no off site locations.

Where is off-site going to be?
Your house?
A hole in my background?

I only own one location.... Thats my house.

I always thought the access times on the SCSI drives were the lowest..

And then there is the low CPU use.
 
Archived from groups: comp.sys.ibm.pc.hardware.storage,comp.periphs.scsi (More info?)

The CPU use is probably better now.
But DMA has nothing to do with SCSI's faster access times.

I now have all SCSI in 1 PC and all IDE in the other.
They have the same MB, CPU, same memory and same OS.

My SCSI is much faster, and is not bogged down in photo shop.

The IDE drivers are UDMA133 type 7200 RPM
My SCSI is 160 type 15k RPM

So there is no reason to upgrade the SCSI drives??

When I am in photoshop, I might open 50 files at once, 20meg each.
These run in batches, the SCSI system blows the IDE away.

And it seems the price per MB is a bit cheaper for the SCSI...
(compared to the Raptor)

You need a network connection between those two PCs and
enough storage (on each) to keep a copy of other PC data.
You might need to run them continously and schedule
automatic data transfer at night (XCOPY might be enough).
Thats all.

What OS are you running?
Most serious OS's nowadays have software RAID 1 facilities, exit MS.
Or you could get yourself a nice SCSI Hostadpter with RAID
functionality, provided you can get the drivers for the OS you use.
That way you can keep the performance bonus SCSI gives you when you use
4 drives.

A definite step back IMHO.

RAID is not as substitute for backup.

SATA and RAID are two different things. Yes you should use removable SATA
drives for backup and no they likely shouldn't be RAID.

> This would not be a major problem if I kept up with my DVD back-ups...

Use removable SATA drives instead of DVD for backups but DVDR backups will
work but are likely too small for convenient operation.

> so I need something automatic and redundant.

Actually you likely need neither. You need redundant backups where one is
always offsite but that's different from redundant storage like RAID 1 or
RAID 5. Having to manually initiate the backup nightly/periodically
shouldn't be too difficult. However automating that process to run
automatically is feasible.

Use something like Acronis TrueImage to create compressend image backups of
the HDs. Direct these image file to removable SATA HDs in trays like
KingWin KF-83(~$30). Get >=2 such SATA HDs and always keep one offsite.

NO, RAID 1 is inexpensively available using MS OSs.

SCSI is very expensive for this purpose. ATA RAID is much less expensive
and is the way to go IF realtime redundancy is needed. Usually such
realtime redundancy is not needed in a home network. HOWEVER even less
expensive backup IS needed.

What bonus does SCSI provide on a home network....none maybe?

A UPS is NOT a replacement for redundant arrays like RAID 1or RAID 5. A UPS
is NOT a replacement for backup.

Then, just create backup scripts and schedule them.
