... for suitable backup software.

I know I've mentioned this before guys but I'm no closer to achieving my aim so if anybody could suggest a solution I'd be grateful.

I backup to two different NAS, with different files going to each one.

Each backup process has to be "Continuous Data Protection" AKA "Real-Time Backup"

At the moment I get this done by using two different products from different manufacturers

What I'd like to do is have one backup software which will allow multiple (ie two) independent CDP backup processes.

Does anybody know of such a holy grail please? Or is there another way that I haven't considered?

Thanks for any ideas

Have you tried Genie Time Line? You can set it up to backup files that have changed on a continuous basis.

Yes Richard, but it only allows one backup job

Had a thought that you want software to mirror your data, so had a little trawl and found this: http://www.backup4all.com/kb/mirror-backup-119.html

Might be worth a look.

Thanks Richard. I really appreciate your help.

Mirror backup isn't what I need unfortunately - it requires a schedule or manual operation My requirements have to be to be CDP.

Time-line, as you said, would have been perfect - if it allowed multiple backup jobs.

Any other ideas gratefully accepted - thanks mate

Acronis do a CDP program, does that fit the bill?

Fraid not David. It only allows for one backup job

Just thinking out loud here...... If your PC has the option to have RAID 1 (I think) it does a drive mirror. So if your data is on a drive that has RAID 0 set up, you have a constant mirror'd backup of that drive at all times, and if you go to RAID 1/0 (again I think) you have a duplicated set of drives that are Mirror'd. This can be setup within windows XP and above if i remember correctly. This would give you full duplication on a continuous basis?? (Again I think)

No, a RAID doesn't prevent from any logical data loss. So a RAID should never be considered as any kind of backup. It's just to prevent an interruption during a harddisk failure. So you'll have time to replace it without loosing new or changed data since your last backup. On servers the disks are hot swappable, so you don't even need to power down the system.

The best protection will be achieved by keeping the backup data on an external system. Even better, if the standard user doesn't have access rights to these data or just a read permission. So the backups cannot be compromised or deleted by malicious software. Therefore create a special user to run the backup tasks. And don't use the admin account for your daily work.

Regarding Paul's question about a suitable backup software, this isn't easy to answer. I presume we're talking about a Windows PC. I haven't found a really good backup software for personal usage yet. There's always a catch. At work we're using NetBackup, but that would be a bit of overkill.

Sorry, Paul, I can't recommend any specific software for now.

Thanks chaps

I use Genie time-line Jürgen. I find it very good but it will only allow a single backup job

Does NetBackup do multiple bsckups and allow for CDP?

We are running NetBackup on dedicated servers and the software is collecting the data from all the other Windows and UNIX servers once a night. For CDP you'd need NetBackup RealTime. But don't ask for the price tag ... maybe it's a bit pricey (but I don't know how much).

Is this because you want to select two different targets as destination?

You could implement your own robocopy jobs to copy a backup from one network storage to another.

Yes, I have two different NAS.

Paul can you not set the one NAS to backup to the second?

No David, the NAS backup completely different data sets

Oh I understand now! I need to stop skim reading so much!

I'll let you off... IF you have the solution

Well, looks like it won't be easy to find a suitable solution.

Jürgen wrote::confused: Well, looks like it won't be easy to find a suitable solution.

Yes, the only way is to use setups from different manufacturers

Surely CDP to multiple locations isn't too much to ask?

Erm...

Have you looked at Sonicwall?

I was about to David, but when I saw that the most basic version cost most of £1000 I didn't go any further.
