Q:How do I recover a file from my Linux VM?
A:Under the /home directory is /home/.snapshot/. This directory has several directories called nightly.x (where x is a number 0 – 14). The directory nightly.14 is a snapshot of the /home directory from 14 days ago. The directory nightly.0 is a snapshot from last night about midnight. One can read from any of these directories.
Q:My MySQL database got corrupted, how do I recover it on Linux?
A:If the database resides on /home, you should be able to stop the database server. You can then copy the relevant database files from the appropriate nightly snapshot and restart the DB server. If your database does not reside on /home or you’re not using snapshots, it would be beneficial to do a nightly backup of the database.
