Copy of LN DB differs in size

(1/3) > >>

booltrue:

I have a 50GB DB on the server, when I do a copy on the server or even a local copy the size is only about 35GB
I figured out that issue long time ago, but for huge DB's it's quite a lot of memory space.

Is there any reason for that issue? The blocksize on the system should not cause such a huge memory space difference.

Peter Klett:
The views need space. Open the copy and you will see that the database becomes bigger

Tode:
The database size consists of:

1. Data in documents
2. Size of Design elements
3. View indexes
4. White space

When you create a new copy only 1. and 2. are the same (although the copy might have / not have document and design compression active, what can make a difference).
3. is built on usage (every view you open will increase the size of your database and every sortable column you click as well)
4. will be reduced automatically when creating a copy (as white space is not copied).

I am quite sure that Peter is right: in a big application view indexes can be almost as big as the data itself.

booltrue:

I just tried to reproduce what both of you said.
I opened all views, clicked on each columns (all are sortable) and opened several documents,
but the size of the database is still the same. It didnt grow up, same as the original one
%used shows 99.9%

Tode:
What about ODS? Are they both the same ODS?
