       jets3t-synchronize - synchronize local directories with an Amazon S3


       Synchronize the contents of a local directory with S3:
         jets3t-synchronize [options] UP <S3path> <path1> [[path2] .. [pathN]]

       Synchronize the contents of S3 with a local directory:
         jets3t-synchronize [options] DOWN <S3path> <download_dir>


       jets3t-synchronize is a console (text mode) Java application for
       synchronizing directories on a computer with an Amazon S3 account.


       -h, --help
         Displays a brief summary with all options.

       -n, --noaction
         No action taken. No files will be changed locally or on S3, instead a
         report will be generating showing what will happen if the command is
         run without the -n option.

       -q, --quiet
         Runs quietly, without reporting on each action performed or
         displaying progress messages. The summary is still displayed.

       -p, --noprogress
         Runs somewhat quietly, without displaying progress messages.  The
         action report and overall summary are still displayed.

       -f, --force
         Force tool to perform synchronization even when files are up-to-date.
         This may be useful if you need to update metadata or timestamps in

       -k, --keepfiles
         Keep outdated files on destination instead of reverting/removing
         them.  This option cannot be used with --nodelete.

       -d, --nodelete
         Keep files on destination that have been removed from the source.
         This option is similar to --keepfiles except that files may be
         reverted.  This option cannot be used with --keepfiles.

       -m, --move
         Move items rather than merely copying them. Files on the local
         computer will be deleted after they have been uploaded to S3, or
         objects will be deleted from S3 after they have been downloaded. Be
         *very* careful with this option.  This option cannot be used with

       -b, --batch
         Download or upload files in batches, rather than all at once.
         Enabling this option will reduce the memory required to synchronize
         large buckets, and will ensure file transfers commence as soon as
         possible. When this option is enabled, the progress status lines
         refer only to the progress of a single batch.

       -s, --skipmetadata
         Skip the retrieval of object metadata information from S3. This will
         make the synch process much faster for large buckets, but it will
         leave jets3t-synchronize with less information to make decisions. If
         this option is enabled, empty files or directories will not be
         synchronized reliably.  This option cannot be used with the --gzip or
         --crypto options.

       -g, --gzip
         Compress (GZip) files when backing up and decompress gzipped files
         when restoring.

       -c, --crypto
         Encrypt files when backing up and decrypt encrypted files when
         restoring. If this option is specified the properties must contain a

       --properties filename
         Load the synchronizer app properties from the given file rather than
         from a file in the classpath.

       --credentials filename
         Load your AWS credentials from an encrypted file, rather than from
         the file. This encrypted file can be created
         using the Cockpit application, or the JetS3t API library.

       --acl ACL_string
         Specifies the Access Control List setting to apply. This value must
         be one of: PRIVATE, PUBLIC_READ, PUBLIC_READ_WRITE. This setting will
         override any acl property specified in the

       --reportlevel level
         A number that specifies how much report information will be printed:

         0 - no report items will be printed (the summary will still be

         1 - only actions are reported

         [Prefixes N, U, D, R, F, M]

         2 - differences & actions are reported

         [Prefixes N, U, D, R, F, M, d, r]

         3 - DEFAULT: all items are reported

         [Prefixes N, U, D, R, F, M, d, r, -]


       Required properties can be provided via: a file named in the classpath (or
       /etc/jets3t/, a file specified with the
       --properties option, or by typing them in when prompted on the command
       line. Required properties are:

       accesskey: Your AWS Access Key (Required)
       secretkey: Your AWS Secret Key (Required)
       password: Encryption password (only required when using crypto)

       Properties specified in this file will override those in (or in /etc/jets3t/


       Report items are printed on a single line with an action flag followed
       by the relative path of the file or S3 object. The report legend

       N: A new file/object will be created

       U: An existing file/object has changed and will be updated

       D: A file/object existing on the target does not exist on the source
       and will be deleted.

       d: A file/object existing on the target does not exist on the source
       but because the --keepfiles or --nodelete option was set it was not

       R: An existing file/object has changed more recently on the target than
       on the source. The target version will be reverted to the older source

       r: An existing file/object has changed more recently on the target than
       on the source but because the --keepfiles option was set it was not

       -: A file is identical between the local system and S3, no action is

       F: A file identical locally and in S3 was updated due to the Force

       M: The file/object will be moved (deleted after it has been copied
       to/from S3).
