NAME
s3qladm - Manage S3QL file systems SYNOPSIS
s3qladm [options] <action> <storage url> where action may be either of passphrase, upgrade, delete or download-metadata. DESCRIPTION
S3QL is a file system for online data storage. Before using S3QL, make sure to consult the full documentation (rather than just the man pages which only briefly document the available userspace commands). The s3qladm command performs various operations on unmounted S3QL file systems. The file system must not be mounted when using s3qladm or things will go wrong badly. The storage url depends on the backend that is used. The S3QL User's Guide should be consulted for a description of the available backends. OPTIONS
The s3qladm command accepts the following options. --debug <module> activate debugging output from <module>. Use all to get debug messages from all modules. This option can be specified multiple times. --quiet be really quiet --log <target> Write logging info into this file. File will be rotated when it reaches 1 MB, and at most 5 old log files will be kept. Specify none to disable logging. Default: none --authfile <path> Read authentication credentials from this file (default: ~/.s3ql/authinfo2) --ssl Always use SSL connections when connecting to remote servers. For backends that allow only encrypted connections, S3QL uses SSL automatically, even if this option is not set. --cachedir <path> Store cached data in this directory (default: ~/.s3ql) --version just print program version and exit Hint: run s3qladm <action> --help to get help on the additional arguments that the different actions take. ACTIONS
The following actions may be specified: passphrase Changes the encryption passphrase of the file system. upgrade Upgrade the file system to the newest revision. delete Delete the file system with all the stored data. download-metadata Interactively download backups of the file system metadata. EXIT STATUS
s3qladm returns exit code 0 if the operation succeeded and 1 if some error occurred. SEE ALSO
The S3QL homepage is at http://code.google.com/p/s3ql/. The full S3QL documentation should also be installed somewhere on your system, common locations are /usr/share/doc/s3ql or /usr/local/doc/s3ql. COPYRIGHT
