Transferring to Biocluster[edit]

  • The core-server is mounted on the biologin nodes at /private_stores/core-server.
  • It is read-only, meaning you can only transfer data from the core-server to Biocluster. You cannot transfer any data from Biocluster to the core-server.


  • The core-server has only a daily snapshot of the filesystem each evening. There is 10 days worth a snapshots. A user is able to go back to a snapshot and copy the data back to their original location in case of accidental deletion.
  • There is no long term backup of data on this machine due to the size of data

Restore data using snapshots[edit]


  • To restore from Windows, go to the folder where the data is missing. Right click on that folder and select Properties. Then select Previous Versions tab. It should list previous versions of the folder you select.
  • Double click on the snapshot you want. Then select the files and directories and copy them back to their original location.
  • The snapshots get erased every 10 days. If you do not copy the data back, then you will not be restoring the data and the snapshot will eventually be lost.

OS X or SFTP[edit]

  • Navigate to the SNAPSHOT directory in the Groups folders
  • Select the date for the data you want to restore
  • Once you have found your data, copy it back to its original location.
  • The snapshots get erased every 10 days. If you do not copy the data back, then you will not be restoring the data and the snapshot will eventually be lost.

Restore data after 10 days[edit]

  • There is no backup of data greater than 10 days due to the amount of data that is stored on the server
