If your Tealeaf system does not use Archive Server, you can use the following method to back up your canister LSSN files.
Verify that no data is still to be added to the LSSN file of interest. For example, if you are backing up data files for yesterday, verify that no spool data is destined for yesterday.
Note: When backing up the session data files, the canister must not be able to access the data files, or those files require a rebuild.
To back up the files with minimal processing server downtime:
- Shut down the Canister Services.
- Create a temporary directory.
- Move the LSSN data files (
lssn*.datandlssn*.idx) of interest into the temporary directory. - Restart the Canister Services.
- Back up the files in the temporary directory.
- Back up the corresponding dtSearch indexes.
- Shut down the Canister Services.
- Move the LSSN files in the temporary directory back into the active
CANISTER.dbsdirectory. - Restart the Canister Services.
When you restore the LSSN files to the live canister, verify that CanTrim is either disabled or the setting for number of days to retain is large enough so that the restored data files are not trimmed on the next startup.
