6 jets3t-synchronize - synchronize local directories with an Amazon S3
7 account
8
10 Synchronize the contents of a local directory with S3:
11 jets3t-synchronize [options] UP <S3path> <path1> [[path2] .. [pathN]]
12 Synchronize the contents of S3 with a local directory:
14 jets3t-synchronize [options] DOWN <S3path> <download_dir>
15
17 jets3t-synchronize is a console (text mode) Java application for
18 synchronizing directories on a computer with an Amazon S3 account.

21 -h, --help
22 Displays a brief summary with all options.
23 -n, --noaction
25 No action taken. No files will be changed locally or on S3, instead a
26 report will be generating showing what will happen if the command is
27 run without the -n option.
28 -q, --quiet
30 Runs quietly, without reporting on each action performed or
31 displaying progress messages. The summary is still displayed.
32 -p, --noprogress
34 Runs somewhat quietly, without displaying progress messages. The
35 action report and overall summary are still displayed.
36 -f, --force
38 Force tool to perform synchronization even when files are up-to-date.
39 This may be useful if you need to update metadata or timestamps in
40 S3.
41 -k, --keepfiles
43 Keep outdated files on destination instead of reverting/removing
44 them. This option cannot be used with --nodelete.
45 -d, --nodelete
47 Keep files on destination that have been removed from the source.
48 This option is similar to --keepfiles except that files may be
49 reverted. This option cannot be used with --keepfiles.
50 -m, --move
52 Move items rather than merely copying them. Files on the local
53 computer will be deleted after they have been uploaded to S3, or
54 objects will be deleted from S3 after they have been downloaded. Be
55 *very* careful with this option. This option cannot be used with
56 --keepfiles.
57 -b, --batch
59 Download or upload files in batches, rather than all at once.
60 Enabling this option will reduce the memory required to synchronize
61 large buckets, and will ensure file transfers commence as soon as
62 possible. When this option is enabled, the progress status lines
63 refer only to the progress of a single batch.
64 -s, --skipmetadata
66 Skip the retrieval of object metadata information from S3. This will
67 make the synch process much faster for large buckets, but it will
68 leave jets3t-synchronize with less information to make decisions. If
69 this option is enabled, empty files or directories will not be
70 synchronized reliably. This option cannot be used with the --gzip or
71 --crypto options.
72 -g, --gzip
74 Compress (GZip) files when backing up and decompress gzipped files
75 when restoring.
76 -c, --crypto
78 Encrypt files when backing up and decrypt encrypted files when
79 restoring. If this option is specified the properties must contain a
80 password.
81 --properties filename
83 Load the synchronizer app properties from the given file rather than
84 from a synchronizer.properties file in the classpath.
85 --credentials filename
87 Load your AWS credentials from an encrypted file, rather than from
88 the synchronizer.properties file. This encrypted file can be created
89 using the Cockpit application, or the JetS3t API library.
90 --acl ACL_string
92 Specifies the Access Control List setting to apply. This value must
93 be one of: PRIVATE, PUBLIC_READ, PUBLIC_READ_WRITE. This setting will
94 override any acl property specified in the synchronize.properties
95 file
96 --reportlevel level
98 A number that specifies how much report information will be printed:
99 0 - no report items will be printed (the summary will still be
101 printed).
102 1 - only actions are reported
104 [Prefixes N, U, D, R, F, M]
106 2 - differences & actions are reported
108 [Prefixes N, U, D, R, F, M, d, r]
110 3 - DEFAULT: all items are reported
112 [Prefixes N, U, D, R, F, M, d, r, -]
114
116 Required properties can be provided via: a file named
117 synchronize.properties in the classpath (or
118 /etc/jets3t/synchronize.properties), a file specified with the
119 --properties option, or by typing them in when prompted on the command
120 line. Required properties are:
121 accesskey: Your AWS Access Key (Required)
123 secretkey: Your AWS Secret Key (Required)
124 password: Encryption password (only required when using crypto)
125 Properties specified in this file will override those in
127 jets3t.properties (or in /etc/jets3t/jets3t.properties).
128
130 Report items are printed on a single line with an action flag followed
131 by the relative path of the file or S3 object. The report legend
132 follows:
133 N: A new file/object will be created
135 U: An existing file/object has changed and will be updated
137 D: A file/object existing on the target does not exist on the source
139 and will be deleted.
140 d: A file/object existing on the target does not exist on the source
142 but because the --keepfiles or --nodelete option was set it was not
143 deleted.
144 R: An existing file/object has changed more recently on the target than
146 on the source. The target version will be reverted to the older source
147 version
148 r: An existing file/object has changed more recently on the target than
150 on the source but because the --keepfiles option was set it was not
151 reverted.
152 -: A file is identical between the local system and S3, no action is
154 necessary.
155 F: A file identical locally and in S3 was updated due to the Force
157 option.
158 M: The file/object will be moved (deleted after it has been copied
160 to/from S3).
