jets3t-synchronize - synchronize local directories with an Amazon
S3 account
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 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- Keep outdated files on destination instead of reverting/removing them.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, -]
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).
