Hi

I am now storing all my family photos on my dns323 and although I have backed up (most) of them I want to be sure that my kids or even myself dont accidentally erase them. I have been trying out folder protection options from windows but these seem to make no difference to the DNS.

Is there a  simple way to protect all my pictures & video from accidental erasure.

thanks in advance,Shum

Simple answer - back them up to another device.  If you don't have a complete backup on separate media then you are asking for trouble.

Long answer - as each folder is completed make it read only via the web interface, or you could set up the relevant permissions for each user as read only with only one user having write permission, again by using the web interface.

The Windows folder protection options will have no effect on the DNS-323, as ivan says, you back it up to a different device.

I want to note also, that whilst his recommendation for setting folders to be read only will prevent accidental deletion, it does not protect from hardware failure.

Oh my God!

I followed your advice (apart from the bit of backing up ALL files) and tried setting a read only for all accounts on a single test folder. Next thing I know I cant see my NAS from any machine or else it says empty volume.

Ive reset the NAS , restarted the computers but it cant be seen. The only thing that is still working is the software which allows me to still set network access on the folders. I then tried removing the read only access  but this has not helped an iota.

Please help!

Sounds like the IP changed.

Well its back up again - I had to set r/w permissions for all users on Volume_1 and it came back to life including the drive mapping -

Im not playing with access again - until I have backed up all my stuff.

I did say each folder. 

The main thing you have learned is the need of a separate backup - most people don't until it is too late.

Make your backup and then experiment with individual folders - not Volume_1, that way you will know what you have done to give you the protection you want and should be able to extend it to other folders.

Hi - maybe a dumb question...

but why, if I have 2 drives in my DNS-323, in a Raid 1 config, would I need to have yet another backup of the data?    Is it likely that both drives would fail at at the same time?     Or  if the DNS-323 itself fails, is my data not still safe, on both drives (or at least one of them)?

Hi Dougweiser,
I am sure there are posts and maybe even a Sticky addressing this issue, but a few things to consider.  Accidental deletion of data, corruption of a file will immediately be corrupted on both drives, a virus, a power surge could wipe out NAS and both drives at the same time, search Raid 1 failure to rebuild.  There are probably a few more reasons.  Some folks with limited storage use their drives as separate volumes and use a local backup of Vol.1 to Vol.2.  Still some risk but a little safer in some ways.  It really depends on how much concern you have about loosing your data.  The more important it is to you the less risk you want to take. I personally backup one NAS to another NAS on a different circuit with a different UPS.  Many businesses have multiple backups including at least one at a remote location.  Hope this answers your question.  Good luck

RAID1 is not a form of backup - It is for hardware redundancy!!!  If does not prevent accidental deletion or overwriting as the changes since the changes are copied across the array.  There are numerous articles discussing the differences between data backup and data redundancy.  I am sure that others will post similar replies to your question.
