The accsyn backend instance orchestrating file transfers/compute jobs across servers and clients.


A user entity, identifying a human interacting with accsyn. See Users.


The user access level defining the base permissions, which can be overridden for global API keys. Three different roles currently exist: Admin, Employee and Standard/restricted(default) user. See Users.

root share

The base folder entity, on a server, that accsyn can server files from. See Shares.


A sub folder entity, beneath a root share, were standard/restricted users can be given access to by a acl. See Shares.


Access Control List entity, normally defining a share (or a directory) beneath a share were a standard/restricted user have download (and upload) access.


A entity which holds a set of tasks - files and/or directories to be synchronized between two network endpoints (P2P), or a compute job for processing data. See Jobs.


A file and/or directory to be synchronized between two network endpoints (P2P), or a compute task for processing data. See Jobs.


A container entity for jobs, having it’s own priority in which jobs are dispatched in queue order. See Queues.


A remote physical location, given an unique name. New servers are assigned the on-prem default “hq” site, desktop clients and user servers are always assigned the “roaming” site, which means the effective site will be detected by analysing the WAN IP of client. During compute job submit, the site is used to determine if synchronization of dependencies are required.

desktop application

The accsyn desktop GUI application, designed for receiving, submitting and monitoring jobs. Represents a client which connects to a remote server during transfer process.


The accsyn server background daemon designed for unattended transmission of data and computations. Represents a client which, in case configured to serve a root share, listens for incoming connections from another app, site server or user server.

site server

A special type of server, responsible for managing file transfer to and from a main server at a remote site, for one or more root shares.

user server

A special type of server, running in user space, for unattended file transfers to and from locally mapped shares/root shares.


An instance of the accsyn desktop application, or background daemon capable of perform file transfers or executing computations.


An entity defining a compute app and its Python wrapper script.


Custom data bound to an entity, in JSON format, divided into an internal (invisible to standard users) and external (visible to all users). Can be used for workflow purposes - are supplied to hooks during execution.
