Manta Archiver is a simple CLI tool that allows you to back up all files from a local directory to a remote Manta path. All files will be stored in Manta in a compressed state with optional encryption provided by the Manta Java SDK.
Manta Archiver is configured in the same fashion as java-manta but provides a way to interactively generate a configuration file so you don't need to learn about java-manta in order to use this project. See the following wiki articles for setup instructions:
Oracle and Azul JVMs require installation of the Java Cryptography Extensions for Oracle JVMs and the Zulu Cryptography Extension Kit for Azul JVMs. This does not apply as of Java 8 update 161, which includes JCE by default for both Oracle and Azul. OpenJDK distributions do not need any modifications to support stronger encryption modes.
If you see the following error it means JCE is required but not installed:
Cannot support TLS_RSA_WITH_AES_256_CBC_SHA256 with currently installed providers
--log-destination: STDOUT, STDERR (default), FILE
--log-level: TRACE, DEBUG, INFO, WARN (default), ERROR
Arguments: [ bits ]
bits: Optional key strength in bits. May be omitted or one of the following:
128,192,256.
Interactively builds a configuration file from a template. If bits is provided the generated configuration will have encryption enabled. See the footnote about encryption strength requirements if selecting a value greater than 128.
This command validates that the utility can connect properly to Manta with the current configuration. Additionally, it outputs the final configuration.

Arguments:
<encryption-strength-bits> <path>bits:
128,192,256(only supported values)
path: path on local filesystem to save key
This command generates an a new encryption key using the specified parameters and saves it to a local path. This is your secret key and it must be proctected.
Arguments:
<path>path: path to key on local filesystem to check
This command validates an existing encryption key to determine if it is a valid key.
Arguments:
<local-directory> <manta-directory>local-directory: the directory path on the local file system to send to Manta
manta-directory: the remote directory path on Manta to upload data to
This command uploads all of the files and directories under the specified directory to Manta to Manta.
Arguments:
<local-directory> <manta-directory>local-directory: the directory path on the local file system to copy files to from Manta
manta-directory: the remote directory path on Manta to download data from
This command downloads all of the directories and files from Manta the specified remote Manta path.
Arguments:
[--fix] <local-directory> <manta-directory>--fix: optional flag that indicates we upload any missing or different files to Manta
local-directory: the directory path on the local file system to copy files to from Manta
manta-directory: the remote directory path on Manta to download data from
This command verifies that the contents of a local directory (files and
directories) match the contents of a remote Manta path. If the --fix flag is
present, then this command will upload any missing files/directories or files
that do not match the remote file. Additionally, this command compares the local
file system with the files stored on Manta.
Arguments:
<manta-directory>
This command verifies that the contents of a remote directory match the checksum stored in Manta's metadata. It does this by downloading each file and performing a checksum on the contents and comparing it to the checksum in the metadata.
