For Nikhef employees we have made available an easy to use laptop backup service called Crashplan. This backup service can be used inside and outside Nikhef. It is strongly recommended that you create a dedicated folder on your laptop where you store all your work related files and that you only backup this work folder on the Nikhef Crashplan server. Be aware of the fact that the backup capacity on the server is limited to 20GB for one laptop per employee. One of the great features of Crashplan is that the backup runs automatically in the background whenever the laptop is active. Additionally to the on-line Crashplan backup it is recommended to make weekly or monthly incremental backups of all files stored in your laptop on a direct attached device like an USB disk.
