NAME

       jets3t-synchronize - synchronize local directories with an Amazon S3 account

SYNOPSIS

       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>

OVERVIEW

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

OPTIONS

       -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 S3.

       -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         Keep outdated files on destination instead of reverting/removing them.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
         --keepfiles.

       -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 password.

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

       --credentials filename
         Load your AWS credentials from an encrypted file, rather than from the
         synchronizer.properties 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 synchronize.properties file

       --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 printed).

         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, -]

NOTES

       Required properties can be provided via: a file named synchronize.properties in the
       classpath (or /etc/jets3t/synchronize.properties), 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 jets3t.properties (or in
       /etc/jets3t/jets3t.properties).

REPORT

       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 follows:

       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 deleted.

       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 version

       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 reverted.

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

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

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