Shadow Copy Feature Request

[bryan]

I have a feature request for the Shadow Copy Format option in Samba Shares. We have multiple levels of snapshots for our data. hourly, daily, monthly. For most shares matching to the daily snapshots for Shadow Copy/previous versions is fine. For the more active shares it would be nice to match on multiple labels. something like:
hourly-%Y%m%d-%H%M%S; daily-%Y%m%d-%H%M%S;

Thanks

Hi Brian,

After thinking a little bit more about it, I may have found a solution to your problem (works with the current version of N4F)...

I guess that you need to code the type of snapshot in your snapshot name in order to handle them differently in your scripts (e.g. in order to keep a certain number of daily snapshots, and delete the older ones).
If that is the case, it is already possible to show all level of snapshot in the windows shadow copy client, but it requires a trick...

code the snapshot type as 2 digits (e.g. "01" for hourly, "02" for daily...)
A snapshot name could be "20121221_1322_autosnapshot_type01"

In the CIFS share config, you only need one label:
d%Y%m%d_%H%M_autosnapshot_type%S
(I tell CIFS that the snapshot type are the seconds. This is not true, but it does not matter as you do not generate snapshot more often then every hour)

Hope that helped

Hi Fritz,

Yes. Thank you. I think I could make that work.
