6 amrecover - Amanda index database browser
7
9 amrecover [-s index-server] [-t tape-server] [-d tape-device]
10 [-h hostname] [-o configoption...] [-C config]
11
13 Amrecover browses the database of Amanda index files to determine which
14 tapes contain files to recover. Furthermore, it is able to recover
15 files.
16 In order to restore files in place, you must invoke amrecover from the
18 root of the backed up filesystem, or use lcd to move into that
19 directory, otherwise a directory tree that resembles the backed up
20 filesystem will be created in the current directory. See the examples
21 below for details.
22 Amrecover will read the amanda-client.conf file and the
24 config/amanda-client.conf file. If no configuration name is supplied on
25 the command line, Amrecover will try the compiled-in default
26 configuration ,usually DailySet1.
27 See the amanda(8) man page for more details about Amanda.
29
31 Note
32 The Default values are those set at compile-time. Use amrestore to
33 recover client-encrypted or client-custom-compressed tapes.
34 [ -C ] config
36 Amanda configuration.
37 -s index-server
39 Host that runs the index daemon.
40 -t tape-server
42 Host that runs the tape server daemon.
43 -d tape-device
45 Tape device to use on the tape server host.
46 -h hostname
48 Hostname to begin restoring; defaults to the system's hostname.
49 -o clientconfigoption
51 See the "CONFIGURATION OVERRIDE" section in amanda(8).
52
54 The default auth is 'BSDTCP', you can set a different auth in the
55 amanda-client.conf file or by specifying the '-oauth=bsd' command line
56 argument.
57
59 Amrecover connects to the index server and then presents a command line
60 prompt. Usage is similar to an ftp client. The GNU readline library is
61 used to provide command line history and editing if it was built in to
62 amrecover.
63 The purpose of browsing the database is to build up a restore list of
65 files to be extracted from the backup system. The following commands
66 are available:
67 sethost hostname
69 Specifies which host to look at backup files for (default: the
70 local host).
71 setdate YYYY-MM-DD-HH-MM[-SS] | YYYY-MM-DD
73 Set the restore time (default: now). File listing commands only
74 return information on backup images for this day, for the day
75 before with the next lower dump level, and so on, until the most
76 recent level 0 backup on or before the specified date is
77 encountered.
78 For example, if:
80 1996-07-01 was a level 0 backup
82 1996-07-02 through 1996-07-05 were level 1 backups
83 1996-07-06 through 1997-07-08 were level 2 backups
84 then the command setdate 1997-07-08-00 would yield files from the
86 following days:
87 1997-07-08 (the latest level 2 backup)
89 1997-07-05 (the latest level 1 backup)
90 1997-07-01 (the latest level 0 backup)
91 Only the most recent version of a file will be presented.
93 The following abbreviated date specifications are accepted:
95 --MM-DD
97 dates in the current year
98 ---DD
100 dates in the current month of the current year
101 setdisk diskname [mountpoint]
103 Specifies which disk to consider (default: the disk holding the
104 working directory where amrecover is started). It can only be set
105 after the host is set with sethost. Diskname is the device name
106 specified in the amanda.conf or disklist(5). The disk must be local
107 to the host. If mountpoint is not specified, all pathnames will be
108 relative to the (unknown) mount point instead of full pathnames.
109 listhost [diskdevice]
111 List all host
112 listdisk [diskdevice]
114 List all diskname
115 listproperty
117 List all property
118 setproperty [append] [priority] name [value ...]
120 Set the property name to the value value. The append keyword
121 appends the value to the values already set for this property.
122 Without value, the property is unset. The priority keyword is
123 unused, it is present for ease of copy/paste from application
124 definition.
125 setdevice [[-h tape-server] tapedev]
127 Specifies the host to use as the tape server, and which of its tape
128 devices to use. If the server is omitted, the server name reverts
129 to the configure-time default. If the tape device is omitted, the
130 default is used.
131 If you want amrecover to use your changer, the tapedev must be
133 equal to the amrecover-changer setting on the server.
134 Since device names contain colons, you must always specify the
136 hostname.
137 settape 192.168.0.10:file:/file1
138 You can change the tape device when amrecover ask you to load the
139 tape:
140 Load tape DMP014 now
141 Continue? [Y/n/t]: t
142 Tape device: server2:/dev/nst2
143 Continue? [Y/n/t]: Y
144 Using tape /dev/nst2 from server server2.
145 setmode mode
147 Set the extraction mode for Samba shares. If mode is smb, shares
148 are sent to the Samba server to be restored back onto the PC. If
149 mode is tar, they are extracted on the local machine the same way
150 tar volumes are extracted.
151 settranslate [on|off]
153 Default: on. Translate escaped octal value ('\000') in the index
154 file to their corespondig characters, it improve the interface if
155 amrecover is run in the same charset as the filename. Set it to off
156 if the charset of some filename is not compatible with the
157 amrecover charset.
158 mode
160 Displays the extracting mode for Samba shares.
161 history
163 Show the backup history of the current host and disk. Dates,
164 levels, tapes and file position on tape of each backup are
165 displayed.
166 pwd
168 Display the name of the current backup working directory.
169 cd dir
171 Change the backup working directory to dir. If the mount point was
172 specified with setdisk, this can be a full pathname or it can be
173 relative to the current backup working directory. If the mount
174 point was not specified, paths are relative to the mount point if
175 they start with "/", otherwise they are relative to the current
176 backup working directory. The dir can be a shell style wildcards.
177 cdx dir
179 Like the cd command but allow regular expression.
180 lpwd
182 Display the amrecover working directory. Files will be restored
183 under this directory, relative to the backed up filesystem.
184 lcd path
186 Change the amrecover working directory to path.
187 ls
189 List the contents of the current backup working directory. See the
190 description of the setdate command for how the view of the
191 directory is built up. The backup date is shown for each file.
192 add item1 item2 ...
194 Add the specified files or directories to the restore list. Each
195 item may have shell style wildcards.
196 addx item1 item2 ...
198 Add the specified files or directories to the restore list. Each
199 item may be a regular expression.
200 delete item1 item2 ...
202 Delete the specified files or directories from the restore list.
203 Each item may have shell style wildcards.
204 deletex item1 item2 ...
206 Delete the specified files or directories from the restore list.
207 Each item may be a regular expression.
208 list file
210 Display the contents of the restore list. If a file name is
211 specified, the restore list is written to that file. This can be
212 used to manually extract the files from the Amanda tapes with
213 amrestore.
214 clear
216 Clear the restore list.
217 quit
219 Close the connection to the index server and exit.
220 exit
222 Close the connection to the index server and exit.
223 extract
225 Start the extract sequence (see the examples below). Make sure the
226 local working directory is the root of the backed up filesystem, or
227 another directory that will behave like that. Use lpwd to display
228 the local working directory, and lcd to change it.
229 help
231 Display a brief list of these commands.

332 The history command shows each tape that has a backup of the current
334 disk along with the date of the backup, the level, the tape label and
335 the file position on the tape. All active tapes are listed, not just
336 back to the most recent full dump.
337 Tape file position zero is a label. The first backup image is in file
339 position one.

360 PAGER The ls and list commands will use $PAGER to display the file
361 lists. Defaults to more if PAGER is not set.
362 AMANDA_SERVER If set, $AMANDA_SERVER will be used as index-server. The
364 value will take precedence over the compiled default, but will be
365 overridden by the -s switch.
366 AMANDA_TAPE_SERVER If set, $AMANDA_TAPE_SERVER will be used as
368 tape-server. The value will take precedence over the compiled default,
369 but will be overridden by the -t switch.
