Duo V1 Disk 1 died Disk 2 all data Install new larger drive?

You can insert the replacement disk into slot 1 while the NAS is running.

Do you have a backup of any important data that is primarily stored on the NAS?

No I don't have any other back up, which is why I was mirroring my data to the 2 drives in the duo. Apart from the apparent need to back up to 3 different types of storage for full protection (or so I read online somewhere) am I like to endanger the data on disk 2 by inserting the new drive?

The sync will put have stress on both disks so if disk 2 also happens to be failing then there is a possibility that the resync could finish it off.

Hi, back again, thanks for the help so far.

Ok so if I go and buy an external drive how do I back up from the NAS disk 2 to an external drive, via Frontview or can I transfer direct from the USB on the duo v1?

Thanks

The fastest way is to connect the USB drive to a PC, and copy the data over ethernet (gigabit preferred). That is quite a bit faster than using the built-in USB connection.

With Windows I'd suggest a copy utility that can verify (for instance teracopy).

Hi again. Ok an update and a request for more help please.

I went and bought a 2TB external hard drive and booted up my Duo V1, ran RAIDar, found the device and got the frontpage up and running.

I then plugged the external HDD into my iMac. However I couldn't figure out how to 'link' my Duo V1 and the external HDD. I flipped around the forum and user guides but couldn't fathom how to transfer data between the two via ethernet this way.

In the end I decided to plug the external HDD into the front USB port and try to back up the whole drive this way.

However whilst the USB Ext HDD was recognised in front page and I could set up a backup job, I couldn't locate a backup job that clearly states 'full or whole' back up. I read in some postings how some backup jobs create more data than just copying the drive contents. I wanted to make sure that my timemachine backups (on the duo v1) were included in task. In the end I decided to create a back up job for c: drive. I set this running and approximately 4 days later it has completed. However the external HDD is showing 730GB of data where as the Duo drive has 920GB on it?

Apologies but can someone clarify how I would backup via ethernet to Ext HDD via my iMac?
How to create a whole or full disk back up/copy?
Why did the backup not copy the same amount as the duo drive?
Where on my Duo V1 are the timemachine backups located.

Remember I am attempting to back up the whole remaining drive from my Duo v1 in order to install a replacement disk (2TB) to further backup and expand the capacity of the Duo V1.

Thanks

The Time Machine backups are in a hidden ".timemachine" directory on the C volume. Is this hidden directory on your backup disk or was it not backed up (note you will need to browse for hidden directories to confirm).

Hi mdgm & thanks for helping.

I've revealed the hidden directories on my backup external HDD and yes ".timemachine" is amongst them. However when I skim through the folders and files listed under ".timemachine" there doesn't appear to be any folders of considerable size to contain my system backups? Is this correct or is this the way apple structures the time machine backups? Thanks

Hi.

I've found a moment to get back online so i'm bumping my problem to see if one of you lovely peeps have any more info or help to give? I'm still at the same point as when I last posted.

Thanks

The sparsebundle in the .timemachine directory is what you want to delete. This contains many directories and files.
