ATE File System is a distributed file system built on top of the ATE distributed datastore. While the author is fully aware that the ecosystem of file-systems is rather saturated this is a good problem to have in the grand scheme of things, this particular varient has some unique qualities that differentiate it from others.
ATE File System uses FUSE to redirect file system commands to a user-space program that responds to IO. This user-space program queries an in-memory distributed database that is synchronized with many consumers and producers. Data is replicated, encrypted, signed and multi-user safe.
Another key property of the ATE File System is that it is totally software defined which allows materialized views of structured non-file based data model to also be represented within the emulated sections of the file system.

sh
sudo apt install cargo make pkg-config libfuse-dev libfuse3-dev openssl libssl-dev
cargo install atefs
```
USAGE:
atefs [FLAGS] [OPTIONS]
FLAGS: -d, --debug Logs debug info to the console --dns-sec Determines if ATE will use DNSSec or just plain DNS -h, --help Prints help information -n, --no-auth No authentication or passcode will be used to protect this file-system --no-ntp No NTP server will be used to synchronize the time thus the server time will be used instead -v, --verbose Sets the level of log verbosity, can be used multiple times -V, --version Prints version information
OPTIONS:
-a, --auth
--dns-server <dns-server>
Address that DNS queries will be sent to [default: 8.8.8.8]
--ntp-pool <ntp-pool>
NTP server address that the file-system will synchronize with
--ntp-port <ntp-port>
NTP server port that the file-system will synchronize with
-t, --token <token>
Token used to access your encrypted file-system (if you do not supply a token then you
will be prompted for a username and password)
--token-path <token-path>
Token file to read that holds a previously created token to be used to access your
encrypted file-system (if you do not supply a token then you will be prompted for a
username and password)
--wire-encryption <wire-encryption>
Indicates if ATE will use quantum resistant wire encryption (possible values are 128,
192, 256). The default is not to use wire encryption meaning the encryption of the event
data itself is what protects the data
SUBCOMMANDS: create-token Logs into the authentication server using the supplied credentials create-user Creates a new user and login credentials on the authentication server help Prints this message or the help of the given subcommand(s) mount Mounts a particular directory as an ATE file system
Creates a new user and login credentials on the authentication server
USAGE:
atefs create-user
ARGS:
FLAGS: -h, --help Prints help information -V, --version Prints version information
Logs into the authentication server using the supplied credentials
USAGE:
atefs create-token
ARGS:
Authenticator code from your google authenticator
FLAGS: -h, --help Prints help information -V, --version Prints version information
Mounts a particular directory as an ATE file system
USAGE:
atefs mount [FLAGS] [OPTIONS]
ARGS:
FLAGS:
--allow-other Allow other users on the machine to have access to this file system
--allow-root Allow the root user to have access to this file system
-h, --help Prints help information
--non-empty Allow fuse filesystem mount on a non-empty directory, default is not
allowed
-r, --read-only Mount the file system in readonly mode (ro mount option), default is
disable
--temp Local redo log file will be deleted when the file system is unmounted,
remotely stored data on any distributed commit log will be persisted.
Effectively this setting only uses the local disk as a cache of the redo-
log while it's being used
-V, --version Prints version information
-w, --write-back Enable write back cache for buffered writes, default is disable
OPTIONS:
--configured-for
--data-format <data-format>
Format of the data in the log file as <bincode>, <json> or <mpack> [default: bincode]
-g, --gid <gid>
GID of the group that this file system will be mounted as
--meta-format <meta-format>
Format of the metadata in the log file as <bincode>, <json> or <mpack> [default:
bincode]
-p, --passcode <passcode>
User supplied passcode that will be used to encrypt the contents of this file-system
instead of using an authentication. Note that this can 'not' be used as combination with
a strong authentication system and hence implicitely implies the 'no-auth' option as
well
--recovery-mode <recovery-mode>
Determines how the file-system will react while it is nominal and when it is recovering
from a communication failure (valid options are 'async', 'readonly-async', 'readonly-
sync' or 'sync') [default: readonly-async]
-u, --uid <uid>
UID of the user that this file system will be mounted as
