[Cytometry] archiving data in a flow core?

Hello Ruth, The policies for archiving data are generated , in the main, by the grant funding bodies, and must be complied to .

We have to ensure that all of our data for certain grants is archived for at least 10 years, some grants for longer. 

If however you are not in receipt of grant specific archive  instruction then we use the following procedure (for us this is suffice for all eventualities. 

1-We use the FCS expert function within Diva to immediately export data once it has been generated onto University data storage , this , because of the architecture of Diva , is also stored on the local computer .

2-At the end of each month  all experiments and the database for the month are exported onto both the local D drive and onto an archival drive(backed up storage) specific for the instrument/moth/year , this is done for all of our 10 flow cytometrs

3-all data is deleted from the Diva database, a defragmentation step takes place , hence each month ,for each instrument we start with a clean database, but have the ability to recall any experiments at any time 

Hope this heps

Dear flow-ers, 

If you are in a flow cytometry core facility, I have a question: What are the policies held by your core regarding data storage & archiving? Specifically: 

-How long are users allowed to leave data on the acquisition computer? 
-How are data files older than this time-period removed from the acquisition computer? 
-Are old files stored as backups by the core? If so, for how long are the backups stored? 

We're getting to the point where it's taking a lot of time and money to archive data that very few people actually ever request, so your advice/experience would be helpful in deciding how to move forward. For reference, we have files collected using CXP, Diva, Spigot, and Summit -- and we will soon also be getting imaging flow cytometry files. 

Thank you,
