- | =====Introduction to the Cloud Drive Concept===== | ||
- | |||
- | Most users are familiar with the concept of cloud file synchronization, | ||
- | An alternative way to access remote data is to provide the user the ability to browse through a list of data available but only download it when it’s actually accessed. | ||
- | |||
- | Enter “FUSE”, a [[https:// | ||
- | |||
- | FUSE-based file systems appear as a regular mount; data is stored locally using a loopback adaptor. | ||
- | |||
- | Changes to a network connection (disconnects, | ||
- | |||
- | FUSE based drive mounts are now commonly used to provide cloud drive like technology and this is what the File Fabric uses to provide its Cloud Drive feature for Mac, Windows and Linux. | ||
- | |||
- | The advantages of a FUSE-based filesystem must be considered with some caveats kept in mind: | ||
- | |||
- | * A network drive based on FUSE has a higher latency than a local file system (it is going off the Cloud after all !). Throughput will be reduced in particular when reading or writing files serially. Use of larger files (Zipped archives) and/or transferring multiple files in parallel can help. | ||
- | |||
- | * Most FUSE-based file systems cache files that are being accessed. There needs to be enough local storage capacity for cached copies of the files and an intelligent cache invalidation mechanism (which is what the File Fabric software provides out of the box, with options to tweak / change these settings). | ||
- | |||
- | * If the remote storage is object based then renaming a directory can result in a long running process in which as files within the folder hierarchy are renamed which can breach the request/ | ||
- | |||
- | * Applications may expect file access to behave a certain way which may result in specific integrations with Application having to be done to enable the FUSE drive to works as expected. The File Fabric drive has some of these integrations built in with Applications such as Microsoft Office and Libre Office, but there may well be some applications that it does not and which may not play well with the drive. | ||
- | |||
- | * There are some settings that need to be turned off to enable the drive to work effectively.Thumbnails is one such feature. Thumbnails require the file to be downloaded to work which negates the premise of not storing the files locally so thumbnail generation is turned off by default (although this too can be changed). | ||
- | |||
- | The benefit of using FUSE based Drives is not only in ease of use but also in the increase in compatibility with third-party software which sees the drive as if it were a local drive, but there is a need to understand and work within the type of limitations that we outline above. |
