Tiers of Storage and Rates
Engram has three storage levels.
...
- From anywhere on Columbia University downtown campus or Manhattanville
- By connecting your computer to the network with a physical network cable
- By using "Columbia U Secure" Wi-Fi
- Note: "Columbia University" Wi-Fi is open and insecure and cannot be used to reach Engram
- From outside the University by using Virtual Private Network (VPN) ( VPN Setup )
- From CUMC: under special circumstances we will work with CUMC IT to open their firewall to allow access to Engram from CUMC locations. Please contact us at rc@zi.columbia.edu
Backing Up Your Data
Data on Engram labshare and locker levels is backed up to tape. We can back up your data on staging storage level if requested.
Tapes are encrypted and periodically moved to a secure offsite location.
Tape backup is the only data protection technology that protects your data against ransomware. Replication (syncing) solutions do not protect against ransomware.
Restoring Your Data
To request data restore please open a restore request by sending email to rc@zi.columbia.edu and tell us:
- The lab you are from
- The directory from which you would like the files to be restored
- A date range (for example, please restore these files from September 15, 2017)
Requesting Access to Existing Storage
If your lab already has a network drive and you need access to it, please send the following information to rc@zi.columbia.edu:
- Your lab name
- Your full name and UNI
- Name of the network drive you need access to
Requesting New Storage
To request new storage please send the following information to rc@zi.columbia.edu:
- How large a network drive you need
- Engram Storage Level (Staging, Labshare or Locker)
- List of UNIs that should have access to this network drive.
Labshare and Locker storage levels are automatically backed up to tape. If you need the Staging storage level to be backed up on tape please mention this in your service request.
Please check the storage pricing above (under "Tiers of Storage and Rates").
Storage protocols.
Engram supports three different types of network drives:
- NFS Exports are chiefly used in Unix/Linux-based server environments. Access to these network drives is based off of the domain name or IP address of the server or workstation that they are to be plugged into. You will need to contact research computing at rc@zi.columbia.edu if you need to mount an NFS export on a host that it is not already mounted on. For each NFS network drive, research computing maintains a whitelist of servers and IP addresses that can mount the network drive. NFS exports are useful if you know that you will only be using your network drive on Linux-based servers and you want to facilitate access to your network drive by server rather than by user account.
- SMB Shares are chiefly used on Mac and Windows workstations, although they can also be attached to Linux servers. For this reason, they are a good option if you expect to need to mount your network share both on workstations and servers. Access to these network drives is based off of your user credentials and the groups that your UNI belongs to in Columbia's user directory. If you need access to an SMB share, you will need to contact research computing to request that your UNI be added to the group associated with that SMB share. SMB shares are not ideal for long-term storage in shared computing environments, since the connection is brokered via an individual user account.
- Hybrid NFS/SMB Network Drives are a more complex arrangement that could make sense under certain circumstances. With a hybrid approach, the same set of files and directories could be made available as an NFS export for a Unix/Linux-based shared server environment and an SMB share for Windows/Mac workstation environments. This approach makes sense if you expect to have your storage connected to both local workstations and a remote server for long periods of time. If you anticipate that you will only need to mount storage on servers on an ad-hoc basis, and that the majority of the time storage will be plugged into workstations primarily, it may make sense to stick with SMB shares alone.
