Previous Versions

[rjm]

Hi there,

 

I am looking to enable previous versions on our staff and student files. Is there a way of calculating how much disk space will be used? I know Server states that it will be a minimum of 300mb just to enable the feature, but what else? Im presuming it uses the actual file as the base and then just saves the changes upto the limit you set?

 

Any pointers or advice would be gratefully received.

 

Cheers

You actually set the limit you want to use for previous versions. The higher you set this the more versions you can store. For example:

 

We set ours to 10gb on each server, and averaging we can usually get around 10 days worth of previous versions (2 versions per day so around 20 different versions) per user before the oldest one is deleted and the space is used for a newer one. We have around 650 students averaging 300mb disk space each, with around 100 staff averaging 1gb each. Any more than the 10 days and it means looking through the backup archives.

 

Hope this helps.

Hi Mate,

 

So when you say 10gb per server, im presuming you mean a 10gb limit for staff, and a 10gb limit for students? We have a total disk usage of 194gb for staff and students combined. So at that amount, 20gb should provide about 10 days?

 

Thanks for the reply.

All users (staff & students) sit on our H: Drive on the server (RM CC3!), so I just allocated 10gb to previous versions on the H: drive and left it at that. Didn't set anything up seperately (i.e. one setting for staff accounts and a different setting for student accounts).

 

It's hard to test previous versions over summer because work areas are not changing. I would set it to 20gb (if you can afford that much) and then see what happens in September when the kids are back. If 20gb is not enough (or too much) then it is a few clicks to increase (or decrease) the setting so is very easy to play with until you have something that suits your needs.
