I am wholly impressed with the speed of file serving on the ReadyNAS Pro. I have 2 NV+, 1 Pro and 15 Duo's installed here and there for different clients.
I would like to migrate some of my larger clients to 1 or 2 ReadyNAS Pro units. We would maintain a single Windows AD server, but the data would be on the ReadyNAS. Several readyNAS units would be mirrored using the R-Sync feature so we have an instant Disaster ready copy!
I have a single issue that is pausing my development process.
My clients are dependent on the Shadow Copy service in Windows. We do weekly full backups and daily differentials of all the data. But, the convenience of being able to select a particular "space in time" to grab a file from is indispensable and they cannot live without it. I understand the snapshot on the ReadyNAS is a single copy. We currently take 2 shadow copies per day. We presently can go back 2-4 weeks to get a file. This is especially useful when a user had deleted a folder by mistake or changed the wrong file. Shadow Copies are incredibly simple to restore from. They make us IT guys look like heroes every time!!
I have researched far and wide for a solution.
Here are the two I have come up with.
1) Create a backup job on the ReadyNAS to sync its data with a Windows 2003 server 2-3 times a day. This would be a one-way sync.
After the backup has run, the Windows server will create a shadow copy of the newly synced data.
I should have multiple shadow copies available now on the Windows server and maintain the disaster copy I am looking for.
I am leaning towards the ReadyNAS as the primary file server for its speed, simplicity, reliability (no Windows) and licensing benefits.
2) I am not familiar with iSCSI as well as I should be. If the ReadyNAS Pro will have iSCSI soon, and I connect a Windows Server using iSCSI...
Can the Windows server create shadow copies of an iSCSI attached device?
Is the raw speed of the ReadyNAS Pro the same via iSCSI being served by a Windows server as if the ReadyNAS Pro was serving the files itself?
Of course, this method brings me back to more Microsoft CAL's...
Am I missing another possible solution?
Is one of these the best there is?
Am I going down the wrong path?
I am looking for raw speed, reliability and reduced licensing.
I am sold on the ReadyNAS reliability and simplicity!!!
Is the ReadyNAS Pro superior in file serving to a Windows 2003 server?
Thanks for your input.
