Disk Space

Information on the disk space available to KIPAC members.

There are several kinds of disk space available at SLAC:
  • Your home directory space. Visible anywhere in the world with a suitably configured AFS client. Introduction to AFS disk space at SLAC. Backed up. Usually about a GB in size, and unlikely to be made larger.
  • AFS data space. This is like your home space, only larger. Usually not backed up. Hosted on various afs servers (see table). Path /afs/slac/g/ki/{ki##,users}.
  • NFS data space. Visible from SLAC NFS clients (ie most SLAC machines). Usually backed up. Hosted on various file servers (Solaris: sulky, wain). Path /nfs/slac/g/ki/ki##.
  • Local space on your desktop. Path usually /u1/username. Only visible from your desktop. Not backed up.

Backup

AFS home directories are backed up. The version from midnight is accessible through the .backup link in your home directory, as described in the "AFS Backup" section of the SLAC Unix Backup page.

Most KIPAC AFS data space is not backed up. To check if your AFS space is backed up, run: fs lq /path/to/your/afs/space. If the output says that the "Volume Name" begins with an uppercase G, then the space is not backed up. If the volume name begins with a lowercase g, then the space is backed up - see the "AFS Backup" section of the SLAC Unix Backup page.

KIPAC NFS space is backed up to tape, using TSM. Retains one or two versions of an existing file. Retains a deleted file for up to a month. Here are the technical details. If you need to restore from a TSM backup, contact unix-admin.

NB: Files under a nobackup directory are excluded from the TSM backup. Please help us save valuable resources by putting non-important files under a nobackup directory, so we do not waste space backing them up.

If you are interesting in archiving/offlining/backing up some of your own files, see the astore howto.
