BACKUP

RFS Access – Samba/CIFS

RFS Access - SFTP

http://iuware.iu.edu

RFS Access - Web

RFS Access – AFS Client

Works with all major operating systems:

Mac, Windows and Linux/Unix

RFS Access

From an off-campus location, IU VPN is required for:

– Samba– AFS client

However, VPN is not needed for:– Web access (https://)– SFTP

Right and wrong ways to use RFS

Good Uses:

• relatively small files (up to ca. 1 GB in size)• files that are updated frequently

– remember that files can be edited directly in RFS, using Samba or the AFS client

• frequently accessed files• files that need to be shared, i.e. group project work

In short, treat RFS like a local hard drive, or a shared drive

Right and wrong ways to use RFS

Poor Uses:

• backups– RFS is intended as workspace, use SDA for backups

and archiving• files updated by multiple users at once

– for example, Access and other databases– files that many users edit simultaneously

SDA introduction: http://kb.iu.edu/data/aiyi.html

Policies

• storage quota for individual users is 100 GB; • additional space may be available upon request

• RFS is available to faculty, staff and graduate students;

undergraduates can be sponsored by faculty or staff

• data are backed up nightly, backups kept for 2 months

• you can request restoration of accidentally lost data

• changes from the previous day:

– kept in the 1day-backup directory

– you can restore data from 1day-backup yourself

• RFS storage system is HIPAA aligned

Collaborative work You can request project space, distinct from your own

user space Initial quota for project spaces is 100 GB You can define your own groups of RFS users

no shared accounts are required

What we will do next:

• We will set up and try out every method of RFS access• We will move files around• We will open and edit files in RFS• We will recover files from the one-day backup• We will share files by using a project space• We will regulate access to project files
