Snapshot of filesystems having containing media files
 

Hi,

I have a filesystem containing many media files such as JPEG, TIFF,
AVI in the mix. Some of these files are heavily edited by users. So,
if I configure hourly snapshots on this filesystem, these files end up
consuming a lot of snapshot space. Now, if I do not configure hourly
snapshots, I am increasing the window of vulnerability for data loss
for the non media files in the filesystem.

One solution that I can think of is to move the media files over to a
new filesystem and not configure hourly snapshots on it. This will
reduce spapshot disk space consumption.

Does anyone have some other interesting way to fix this problem ?

Thanks in advance,
Chandan

Might help if you described the environment a little more, i.e. storage
vendors, whose snapshot are you using etc. Some snapshots are more
inefficient than others.

Do you have different recovery point objectives for your media and non-
media files ? If so, separating the two types into their own file
system on their own volume
sounds like a fine first step.
But if the non-media files are dependent on the media files (e.g. web
pages contain urls to the jpegs), restoring to two different points in
time might not be possible.

I am using NetApp.
