RE: Backing up the ArchiverStores STS MTS LTS Epic Archiver Appliance

["Manoussakis, Adamandios via Tech-talk" <tech-talk at aps.anl.gov>]

Thanks Murali/Ralph, will play around with moving those files out then.  Just to follow up would I be able to place these exact files back into a blank AA LTS folder for example and be able to access them through an archive viewer like normal?

 

Andy, I had some follow up questions to what you said about how the STS MTS and LTS work.  So each time the protobuf gets moved from STS > MTS then ends up in LTS, it will just pile up in LTS that correct?  Like you said if I just move out the LTS files to back them up that would probably alleviate the issue of taking up too much space.  

 

Thanks,

Adam

Given the usual caveats about some processes deleting files while other processes are writing/reading from them; you can operate on these files independent of the archiver. So, in some cases, you might see some exceptions about missing files etc but otherwise things should continue to function as usual. Hope this answers the question...

Don't understand this question though. The files here contain actual data; if you delete these files; you will be losing data.

 

I think the question can be rephrased as: Can you safely move away the files?
