# Reinstall Server From Recovery Disk with RSYNC

Few weeks ago, my Amsterdam instance out of space. My all projects is in my workstation (also Github and Gitlab) and I make a sync with mirrorfy to server.

Normally I have to write truncate command with */* arg while in /var/log folder to truncate files but lack of sleep cause to write a /*/* and most of the binaries and some important system files is gone 😂.
