NAME

       cback3-amazons3-sync - Synchronize a local directory with an Amazon S3 bucket

SYNOPSIS

       cback3-amazons3-sync [switches] sourceDir s3BucketUrl

DESCRIPTION

       This  is  the Cedar Backup 3 Amazon S3 sync tool.  It synchronizes a local directory to an
       Amazon S3 cloud storage bucket.  After the sync is complete, a validation step  is  taken.
       An  error  is reported if the contents of the bucket do not match the source directory, or
       if the indicated size for any file differs.

       Generally, one can run the cback3-amazons3-sync command with no  special  switches.   This
       will  start  it  using  the  default Cedar Backup log file, etc.  You only need to use the
       switches if you need to change the default behavior.

MIGRATING FROM VERSION 2 TO VERSION 3

       The main difference between Cedar Backup version 2 and  Cedar  Backup  version  3  is  the
       targeted  Python  interpreter.   For most users, migration should be straightforward.  See
       the discussion found at cback3(1) or reference the Cedar Backup user guide.

ARGUMENTS

       sourceDir
              The source directory on a local disk.

       s3BucketUrl
              The URL  specifying  the  location  of  the  Amazon  S3  cloud  storage  bucket  to
              synchronize with, like s3://example.com-backup/subdir.

SWITCHES

       -h, --help
              Display usage/help listing.

       -V, --version
              Display version information.

       -b, --verbose
              Print verbose output to the screen as well writing to the logfile. When this option
              is enabled, most information that would normally be written  to  the  logfile  will
              also be written to the screen.

       -l, --logfile
              Specify   the   path  to  an  alternate  logfile.   The  default  logfile  file  is
              /var/log/cback3.log.

       -o, --owner
              Specify the ownership  of  the  logfile,  in  the  form  user:group.   The  default
              ownership  is root:adm, to match the Debian standard for most logfiles.  This value
              will only be used when creating a new logfile.  If the logfile already exists  when
              the  cback3  script  is  executed,  it will retain its existing ownership and mode.
              Only user and group names may be used, not numeric uid and gid values.

       -m, --mode
              Specify the permissions for the logfile, using the numeric  mode  as  in  chmod(1).
              The default mode is 640 (-rw-r-----).  This value will only be used when creating a
              new logfile.  If the logfile already exists when the cback3 script is executed,  it
              will retain its existing ownership and mode.

       -O, --output
              Record  some  sub-command  output  to the logfile. When this option is enabled, all
              output from system commands will be logged. This might be useful for  debugging  or
              just for reference.

       -d, --debug
              Write  debugging  information to the logfile. This option produces a high volume of
              output, and would generally only be needed when debugging a  problem.  This  option
              implies the --output option, as well.

       -s, --stack
              Dump  a  Python  stack  trace  instead of swallowing exceptions.  This forces Cedar
              Backup to dump the entire Python stack trace associated with an error, rather  than
              just  progating last message it received back up to the user interface.  Under some
              circumstances, this is useful information to include along with a bug report.

       -D, --diagnostics
              Display runtime diagnostic information and then exit.  This diagnostic  information
              is often useful when filing a bug report.

RETURN VALUES

       This  command  returns  0  (zero)  upon  normal  completion, and several other error codes
       related to particular errors.

       1      The Python interpreter version is < 3.4.

       2      Error processing command-line arguments.

       3      Error configuring logging.

       5      Backup was interrupted with a CTRL-C or similar.

       6      Other error during processing.

NOTES

       This tool is a wrapper over the Amazon AWS CLI interface  found  in  the  aws(1)  command.
       Specifically,   cback3-amazons3-sync   invokes  "aws  s3  sync"  followed  by  "aws  s3api
       list-objects".

       Cedar Backup itself is designed to run as root.  However, cback3-amazons3-sync can be  run
       safely  as  any  user  that is configured to use the Amazon AWS CLI interface.  The aws(1)
       command will be executed by the same user which is executing cback3-amazons3-sync.

       You must configure the AWS  CLI  interface  to  have  a  valid  connection  to  Amazon  S3
       infrastructure  before  using  cback3-amazons3-sync.  For  more  information  about how to
       accomplish this, see the Cedar Backup user guide.

BUGS

       If you find a bug, please report it.

       If possible, give me the output from --diagnostics, all of the  error  messages  that  the
       script  printed  into its log, and also any stack-traces (exceptions) that Python printed.
       It would be even better if you could tell me how to reproduce the problem, for instance by
       sending me your configuration file.

       Report bugs to <support@cedar-solutions.com> or by using the BitBucket issue tracker.
