ARCHIVER Data storage
The short term storage differs from medium/long term locations for the following reasons (Thanks to P. Reimer for pointing this out)
- Primarily, if there are network problems, they may effect some links, but at least the Archiver will still be able to store whatever data EPICS has that is valid, regardless of whether or not /data2 is reachable.
- If there are network problems, the Archiver will still have access to recent (which we can define) data to serve to which ever clients can reach it regardless of whether or not /data2 is reachable.
- The Archiver will respond slightly faster as there is one network hop that it will not have to do when storing or reading data.
Short term: /home/epics/archiver/archappl/sts
Medium Term: /data2/e1039_data/slowcontrol_data/epics_archiver/mts
Long term: /data2/e1039_data/slowcontrol_data/epics_archiver/lts
