Hi!

I did a Google search and found this We would be very excited to get anyone a copy of the software who would like to try it out.

Please contact me directly at brooke@r1soft.com

We are looking forward to your evaluation and feedback!

Peter –

The things I like:
1. Can be dropped into an existing system (no LVM required, no refactoring storage to make it work)
2. Very little performance overhead, reads at the block level, doesn’t push anything out of the disk cache (to us, a very important concern)
3. Can be used to set up a slave or secondary master without any downtime
4. Enables me to take backups as often as I want (I take backups every 3 hours, though I could do it more often)
5. Only needs a short table lock, and then an unlock, and it’s able to backup from there
6. Supports both windows and linux for a homogenous enviroment

Things I don’t like:
1. Only supports ext2/3 and reiserfs (currently)

@Brian – I’m suprised, they’re very quick to respond to technical problems, maybe sales is a different story, I’ll be happy to show you around our copy if you want, I can easily create a user for you.

Michael, I also reached out to R1Soft to see if they were interested in letting us have access to a system to evaluate so we would be able to knowledgeably recommend it when appropriate (we do not just repeat sales brochures to our clients). There was no reply.

Michael,

Thanks. We have some customers using it and we have had a work to give it a good test for some time – what kind of overhead does it have, what are performance parameters etc.

At the same time I really would like to see some Open Source solution as an alternative.

Yep, that’s exactly what I meant. So the tool would have to work with LVM snapshots, correct? Just wondering.

This information is stored in files so it can be perfectly accessed by external tool. The LVM Backup or other snapshot suggested is to ensure the state of files is atomic.

> The Innodb pages have great deal of information helpful for their incremental backup in their internal.

I wonder if that information can be *properly* accessed by an external tool, or whether the tool will need to be built into MySQL.

I’ve recommended it many times before here in the comments section:

(No, I have no association with this company). We use a product called CDP by a company named R1Soft. http://www.r1soft.com/

It works EXTREMELY well for incremental mysql backups (no need for lvm, etc). We’ve been using it for a year, and it “just works”.

I highly recommend you try it.
