Visual representation of a local backup

A system comprising:

• one or more computing devices operable to perform operations including:
• receiving a user input to present a visual representation of a first prior state of a file system, where the file system comprises one or more data items organized according to a hierarchy;
• generating the first visual representation of a first prior state of the file system, wherein generating the first visual representation comprises:
• determining a first result set based on a comparison between the file system and a first virtual file system associated with the first prior state of the file system;
• and
• generating the first visual representation based on the result set,
• wherein the first virtual file system comprises one or more hierarchically organized elements, the elements indicating changes introduced to the file system after a first time point associated with the first prior state of the file system;
• presenting the first visual representation, the first visual representation comprising a user-navigable representation of the data items and the hierarchy of the file system according to the first prior state;
• receiving a user input to present a second visual representation of a second prior state of the file system;
• generating the second visual representation of the second prior state of the file system, wherein generating the second visual representation comprises:
• determining a second result set based on a comparison between the first result set and a second virtual file system associated with the second prior state of the file system;
• and
• generating the second visual representation based on the second result set,
• wherein the second virtual file system comprises one or more hierarchically organized elements, the elements indicating changes introduced to the file system after a second time point associated with the second prior state of the file system;
• presenting the second visual representation, the second visual representation comprising a user-navigable representation of the data items and the hierarchy of the file system according to the second prior state;
• receiving an input to restore a particular data item presented in the first visual representation or the second visual representation;
• identifying backup data corresponding to the particular presented data item;
• and
• restoring the backup data to the file system.

A non-transitory computer storage medium encoded with a computer program, the program comprising instructions that when executed by data processing apparatus cause the data processing apparatus to perform operations comprising:

• receiving a user input to present a visual representation of a first prior state of a file system, wherein the system comprises one or more data items organized according to a hierarchy;
• generating the first visual representation of a first prior state of the file system, wherein generating the first visual representation comprises:
• determining a first result set based on a comparison between the file system and a first virtual file system associated with the first prior state of the file system;
• and
• generating the first visual representation based on the result set,
• wherein the first virtual file system comprises one or more hierarchically organized elements, the elements indicating changes introduced to the file system after a first time point associated with the first prior state of the file system;
• presenting the first visual representation, the first visual representation comprising a user-navigable representation of the data items and the hierarchy of the file system according to the first prior state;
• receiving a user input to present a second visual representation of a second prior state of the file system;
• generating the second visual representation of the second prior state of the file system, wherein generating the second visual representation comprises:
• determining a second result set based on a comparison between the first result set and a second virtual file system associated with the second prior state of the file system;
• and
• generating the second visual representation based on the second result set,
• wherein the second virtual file system comprises one or more hierarchically organized elements, the elements indicating changes introduced to the file system after a second time point associated with the second prior state of the file system;
• presenting the second visual representation, the second visual representation comprising a user-navigable representation of the data items and the hierarchy of the file system according to the second prior state;
• receiving an input to restore a particular data item presented in the first visual representation or the second visual representation;
• identifying backup data corresponding to the particular presented data item from the first virtual file system;
• and
• restoring the backup data to the file system.
