Hello.
There is a parameter in the archive tab of a Trend display called "Delete old Archive". If that parameter is set, the Archive is deleted after Freelance Operations has been closed and is restarted again.
If it is not checked the archive will be resumed with a corresponding time gap after restart of Freelance Operations.
Also in that case it can appear the data has been deleted, if your parameter "Archive Duration" is smaller (let's say 3 days f.e.) than your downtime of Freelance operations (let's say 5 days f.e.).
In case you have modified the Trend while Freelance Operations was down, for example the number of signals archived has changed, or the data type of one signal has changed, Then the old archive is closed and a new archive file is started. The old archive can still be found in the "curv" directory having a serial extension after the file name starting with 001. You can open this file with the "Archive Browser" tool.
