Software & Services
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.
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 create a tunnel for connecting to a rsync daemon. Each time this tunnel has been disconnected (e.g. reboot of your machine or a VSC login node) you have to re-login with a OTP to reestablish the ssh tunnel
Do the following steps:
wget https://wiki.vsc.ac.at/lib/exe/fetch.php?media=doku:rsync:rsyncd_setup_remote.sh -O 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 -O rsyncd_setup_local.sh bash rsyncd_setup_local.sh
rsync --daemon --config=/home/ ..../ rsyncd.conf
ssh -L 5100:l32.cm.cluster:8077 <user>@l32.vsc.ac.at
(the login node “l32” conntected to must be the same as in step 3)
rsync --password-file=/home/.../rsyncd.secrets -av --port 5100 rsync://<user>@localhost/myfiles /tmp/
