Backup

User Data on VSC is not backuped.

Backup is solely the responsibility of each user.

RAID-5 or RAID-6 is used on NFS and FhGFS servers to protect against single disk failure. Up to one (RAID-5) or two (RAID-6) disks failing concurrently can be sustained.

Other failure modes like disk controller failure or filesystem software faults are very seldom but might lead to loss of data.

Continous Backup of user Data to remote Machines

A continuous backup from VSC has to circumvent the entering of the OTP numbers. If it its possible to keep a ssh session alive for a longer time, it can be used to tunnel the connection to a rsync daemon.

Do the following steps:

  1. on the remote machine:
    wget https://wiki.vsc.ac.at/lib/exe/fetch.php?media=doku:rsync:rsyncd_setup_remote.sh
    bash rsyncd_setup_remote.sh
wget https://wiki.vsc.ac.at/lib/exe/fetch.php?media=doku:rsync:rsyncd_setup_local.sh
bash rsyncd_setup_local.sh
