Abstract

Techniques for populating a new synchronization (“sync”) folder during an upgrade of a sync client of a cloud-based platform includes transferring synced items stored at a first location to an archive location in response to an indication to upgrade the sync client, detecting an instruction to populate the new sync folder at a second location with an item, determining that the synchronization client is in migration mode and transferring a local copy of the item from the archive location to the new sync folder to populate the new sync folder at the second location when the local copy of the item has the same state as a remote copy of the item at the cloud-based platform. Also disclosed are techniques for accommodating autoupdate operations, monitoring performance of sync operations and providing a tray icon that provides a high level overview of the state of a sync operation.

Claims

1. A method of populating a new synchronization folder during an upgrade of a synchronization client of a cloud-based platform, comprising:

receiving a command for upgrading the synchronization client on a client device to a new version, wherein the synchronization client updates a synchronization folder storing a local copy of items in a collaboration workspace stored on the client device and a remote copy of the items in the collaboration workspace stored on the cloud-based platform, wherein upgrading the synchronization client to the new version is distinct from causing the updates between the local copy of the item on the client device and the remote copy of the item on the cloud-based platform and wherein upgrading the synchronization client to the new version changes a location of the synchronization folder from a first location on the client device to a second location on the client device;

backing up the items stored at the first location on the client device to an archive location on the client device;

identifying a location of a parent folder for the items stored at the first location on the client device;

modifying a path to the location of the parent folder, wherein the modifying maps the location of the parent folder from the archive location;

in response to the command for upgrading the version of the synchronization client, creating the new synchronization folder at the second location on the client device; and

upon creation of the new synchronization folder, populating the new synchronization folder by;

comparing states of items stored remotely under an account in a database of the cloud-based platform with states of the items stored at the archive location;

identifying, based on the comparing of the states of items, items with matching states and one or more items with mismatched states; and

transferring automatically the items with matching states from the archive location to the new synchronization folder, whereby the transferring automatically includes (i) the items with matching states to appear in the new synchronization folder and disappear from the archive location and (ii) the one or more items with mismatched states to remain stored in the archive location.

2. The method of claim 1, the populating further comprising:

downloading the one or more items with mismatched states from the database of the cloud-based platform to populate the new synchronization folder.

3. The method of claim 2, wherein the one or more items with mismatched states includes (i) an item stored locally at the archive location having a state different from a state of the item stored remotely in the database of the cloud-based platform or (ii) an item stored remotely in the database of the cloud-based platform that does not have a corresponding item stored locally at the archive location.

4. The method of claim 1, wherein a state of each item is determined based on a hash of the item.

5. The method of claim 4, wherein a hash of an item stored locally at the archive location is obtained by calculation or from a cache of hashes.

6. The method of claim 4, wherein a hash of an item stored remotely in the database of the cloud-based platform is obtained from a remote file system shadow that provides a current state of all files and folders under the account stored in the database of the cloud-based platform.

7. The method of claim 5, wherein obtaining the hash of the item from the cache of the hashes includes:

checking a file including one or more pre-calculated hashes, a filename, and timestamp data to lookup a pre-calculated hash of the item;

determining that a timestamp for the pre-calculated hash is greater than a timestamp for the item stored locally at the archive location; and

foregoing calculation of the hash of the item by using the pre-calculated hash for the comparing.

8. The method of claim 1, wherein populating the new synchronization folder with an item is in response to a create event for the item.

9. The method of claim 1, wherein the new synchronization folder is at a second location on the client device different from the first location and the archive location.

10. A non-transitory computer readable medium storing instructions configured to, when executed by a client computing device, cause the computing device to perform the method of populating a new synchronization folder during an upgrade of a synchronization client of a cloud-based platform, comprising instructions for:

receiving a command for upgrading the synchronization client on a client device to a new version, wherein the synchronization client updates a synchronization folder storing a local copy of items in a collaboration workspace stored on the client device and a remote copy of the items in the collaboration workspace stored on the cloud-based platform, wherein upgrading the synchronization client to the new version is distinct from causing the updates between the local copy of the item on the client device and the remote copy of the item on the cloud-based platform and wherein upgrading the synchronization client to the new version changes a location of the synchronization folder from a first location on the client device to a second location on the client device;

backing up the items stored at the first location on the client device to an archive location on the client device;

identifying a location of a parent folder for the items stored at the first location on the client device;

modifying a path to the location of the parent folder, wherein the modifying maps the location of the parent folder from the archive location;

in response to the command for upgrading the synchronization client, creating the new synchronization folder at the second location on the client device; and

upon creation of the new synchronization folder, populating the new synchronization folder by;

comparing states of items stored remotely under an account in a database of the cloud-based platform with states of the items stored;

identifying, based on the comparing of the states of items, items with matching states and one or more items with mismatched states; and

transferring automatically the items with matching states from the archive location to the new synchronization folder, whereby the transferring automatically includes (i) the items with matching states to appear in the new synchronization folder and disappear from the archive location and (ii) the one or more items with mismatched states to remain stored in the archive location.

11. The medium of claim 10, wherein the instructions further comprise instructions for:

downloading the one or items with mismatched states from the database of the cloud-based platform to populate the new synchronization folder.

12. The medium of claim 11, wherein the one or more items with mismatched item includes (i) an item stored locally at the archive location having a state different from a state of the item stored remotely in the database of the cloud-based platform or (ii) an item stored remotely in the database of the cloud-based platform that does not have a corresponding item stored locally at the archive location.

13. The medium of claim 10, wherein a state of each item is determined based on a hash of the item.

14. The medium of claim 13, wherein a hash of an item stored locally at the archive location is obtained by calculation or from a cache of hashes.

15. The medium of claim 13, wherein a hash of an item stored remotely in the database of the cloud-based platform is obtained from a remote file system shadow that provides a current state of all files and folders under the account stored in the database of the cloud-based platform.

16. The medium of claim 14, wherein instructions for obtaining the hash of the item from the cache of the hashes includes instructions for:

checking a file including one or more pre-calculated hashes, a filename, and timestamp data to lookup a pre-calculated hash of the item;
