Distributed recovery of server information

A method comprising:

• receiving, by one or more processors of a first computing device, from a server, an indication that the server has recovered backed up metadata to a server metadata database maintained by the server, wherein the first computing device stores, in a first metadata database, first metadata including a file system mapping for one or more file systems accessed by one or more client devices via the first computing device, wherein a second computing device is configured to store, to a second metadata database, a copy of the file system mapping stored by the first computing device;
• based on the server having performed recovery of the backed up metadata to the server metadata database, receiving, by the first computing device, from the server, a recovered file system mapping of the one or more file systems determined by the server from the backed up metadata recovered by the server;
• in response to receiving from the server the recovered file system mapping determined from the recovered backed up metadata, comparing, by the first computing device, the recovered file system mapping received from the server with the file system mapping of the one or more file systems stored by the first computing device in the first metadata database, wherein the comparing by the first computing device comprises comparing each share path and file system identifier in the recovered file system mapping from the server with each share path and file system identifier in the file system mapping on the first computing device;
• and
• sending, by the first computing device, to the server, information about changes determined between the file system mapping stored by the first computing device and the recovered file system mapping received from the server to enable the server to update the recovered file system mapping in the server metadata database based on the information about the changes determined between the file system mapping stored by the first computing device and the recovered file system mapping received from the server.

One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors of a first computing device, program the one or more processors to perform operations comprising:

• receiving, by the first computing device, from a server, an indication that the server has recovered backed up metadata to a server metadata database maintained by the server, wherein the first computing device stores, in a first metadata database, first metadata including a file system mapping for one or more file systems accessed by one or more client devices via the first computing device, wherein a second computing device is configured to store, to a second metadata database, a copy of the file system mapping stored by the first computing device;
• based on the server having performed recovery of the backed up metadata to the server metadata database, receiving, by the first computing device, from the server, a recovered file system mapping of the one or more file systems determined by the server from the backed up metadata recovered by the server;
• in response to receiving from the server the recovered file system mapping determined from the recovered backed up metadata, comparing, by the first computing device, the recovered file system mapping received from the server with the file system mapping of the one or more file systems stored by the first computing device in the first metadata database, wherein the comparing by the first computing device comprises comparing each share path and file system identifier in the recovered file system mapping from the server with each share path and file system identifier in the file system mapping on the first computing device;
• and
• sending, by the first computing device, to the server, information about changes determined between the file system mapping stored on the first computing device and the recovered file system mapping received from the server to enable the server to update the recovered file system mapping in the server metadata database based on the information about the changes determined between the file system mapping stored by the first computing device and the recovered file system mapping received from the server.
