Hi,
bellow is a set of questions that poped in my head after reading documentation and some test with deduplication, DP 9.0:
- (1)does deduplication also compress the chunks?
- (2) How can I tune logging of storeoncesoftware service? The command line options lists –-log_path and –-log_level are documented to adjust logging however it is not easy to pass them to the storeoncesoftware windows service. The only option that worked for me is to use "sc start storeoncesoftware --log_path=... --log_level=...". I did not found a way to make the settings permanent. Without any setting the logs are stored in OmniBack\tmp folder. Default level is not documented, with "information" it logs too much and with "notice" almost nothing. The process also logs into Windows EventLog, see bellow
- (3) My EventLog gets spammed with warnings about low memory (starting at 25%), in certain times I get 1 warning message per second and EventLog is filled up with useless data. Can I adjust the warning level? Can I get the warning only when the free memory percentage changes instead of bursts of warnings with the same % level in few seconds? Can I get the warning written to log files?
+0200 2014-09-04 23:42:48 StoreOnceSoftware is near the memory capacity limit,
Free memory left: 24%
- (4) How can I manually initiate store housekeeping procedures? Say I want to empty the store, this is my current procedure:
- delete all sessions stored in storage
- export all storage media
- ** now I want to manually initiate housekeeping procedures so the store is physically emptied but instead I have to do the next steps **
- delete the device
- stop the store and delete the store using storeoncessoftware CLI (sometimes stop doesn't work, service stop/start is needed)
- after store is deleted, storeoncesoftware physically removes the data and store is emptied
- recreate the device and store
- (5) how can I reinitialize the storeoncesoftware so that new store root must be created? Someone (probably me) deleted some important file from the store and found no way how to reinitialize it. I had to uninstall StoreOnceSoftware, delete store root and reinstall StoreOnceSoftware.
- (6) Several times I got strange errors from storeoncesoftware once the backups were done. I have found no log entries on the storeoncesoftware node, just pool medium status is Inactive/Aborted. All the session data were delete from the store (store is empty).
