6 amrecover - Amanda index database browser
7
9 amrecover [-C config] [-s index-server] [-t tape-server]
10 [-d tape-device] [-h hostname] [-o configoption]...
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 Amrecover connects to the index server and then presents a command line
55 prompt. Usage is similar to an ftp client. The GNU readline library is
56 used to provide command line history and editing if it was built in to
57 amrecover.
58 The purpose of browsing the database is to build up a restore list of
60 files to be extracted from the backup system. The following commands
61 are available:
62 sethost hostname
64 Specifies which host to look at backup files for (default: the
65 local host).
66 setdate YYYY-MM-DD-HH-MM[-SS] | YYYY-MM-DD
68 Set the restore time (default: now). File listing commands only
69 return information on backup images for this day, for the day
70 before with the next lower dump level, and so on, until the most
71 recent level 0 backup on or before the specified date is
72 encountered.
73 For example, if:
75 1996-07-01 was a level 0 backup
77 1996-07-02 through 1996-07-05 were level 1 backups
78 1996-07-06 through 1997-07-08 were level 2 backups
79 then the command setdate 1997-07-08-00 would yield files from the
81 following days:
82 1997-07-08 (the latest level 2 backup)
84 1997-07-05 (the latest level 1 backup)
85 1997-07-01 (the latest level 0 backup)
86 Only the most recent version of a file will be presented.
88 The following abbreviated date specifications are accepted:
90 --MM-DD
92 dates in the current year
93 ---DD
95 dates in the current month of the current year
96 setdisk diskname [mountpoint]
98 Specifies which disk to consider (default: the disk holding the
99 working directory where amrecover is started). It can only be set
100 after the host is set with sethost. Diskname is the device name
101 specified in the amanda.conf or disklist(5). The disk must be local
102 to the host. If mountpoint is not specified, all pathnames will be
103 relative to the (unknown) mount point instead of full pathnames.
104 listhost [diskdevice]
106 List all host
107 listdisk [diskdevice]
109 List all diskname
110 listproperty
112 List all property
113 setproperty [append] [priority] name [value ...]
115 Set the property name to the value value. The append keyword
116 appends the value to the values already set for this property.
117 Without value, the property is unset. The priority keyword is
118 unused, it is present for ease of copy/paste from application
119 definition.
120 setdevice [[-h tape-server] tapedev]
122 Specifies the host to use as the tape server, and which of its tape
123 devices to use. If the server is omitted, the server name reverts
124 to the configure-time default. If the tape device is omitted, the
125 default is used.
126 If you want amrecover to use your changer, the tapedev must be
128 equal to the amrecover_changer setting on the server.
129 Since device names contain colons, you must always specify the
131 hostname.
132 settape 192.168.0.10:file:/file1
133 You can change the tape device when amrecover ask you to load the
134 tape:
135 Load tape DMP014 now
136 Continue? [Y/n/t]: t
137 Tape device: server2:/dev/nst2
138 Continue? [Y/n/t]: Y
139 Using tape /dev/nst2 from server server2.
140 setmode mode
142 Set the extraction mode for Samba shares. If mode is smb, shares
143 are sent to the Samba server to be restored back onto the PC. If
144 mode is tar, they are extracted on the local machine the same way
145 tar volumes are extracted.
146 mode
148 Displays the extracting mode for Samba shares.
149 history
151 Show the backup history of the current host and disk. Dates,
152 levels, tapes and file position on tape of each backup are
153 displayed.
154 pwd
156 Display the name of the current backup working directory.
157 cd dir
159 Change the backup working directory to dir. If the mount point was
160 specified with setdisk, this can be a full pathname or it can be
161 relative to the current backup working directory. If the mount
162 point was not specified, paths are relative to the mount point if
163 they start with "/", otherwise they are relative to the current
164 backup working directory. The dir can be a shell style wildcards.
165 cdx dir
167 Like the cd command but allow regular expression.
168 lpwd
170 Display the amrecover working directory. Files will be restored
171 under this directory, relative to the backed up filesystem.
172 lcd path
174 Change the amrecover working directory to path.
175 ls
177 List the contents of the current backup working directory. See the
178 description of the setdate command for how the view of the
179 directory is built up. The backup date is shown for each file.
180 add item1 item2 ...
182 Add the specified files or directories to the restore list. Each
183 item may have shell style wildcards.
184 addx item1 item2 ...
186 Add the specified files or directories to the restore list. Each
187 item may be a regular expression.
188 delete item1 item2 ...
190 Delete the specified files or directories from the restore list.
191 Each item may have shell style wildcards.
192 deletex item1 item2 ...
194 Delete the specified files or directories from the restore list.
195 Each item may be a regular expression.
196 list file
198 Display the contents of the restore list. If a file name is
199 specified, the restore list is written to that file. This can be
200 used to manually extract the files from the Amanda tapes with
201 amrestore.
202 clear
204 Clear the restore list.
205 quit
207 Close the connection to the index server and exit.
208 exit
210 Close the connection to the index server and exit.
211 extract
213 Start the extract sequence (see the examples below). Make sure the
214 local working directory is the root of the backed up filesystem, or
215 another directory that will behave like that. Use lpwd to display
216 the local working directory, and lcd to change it.
217 help
219 Display a brief list of these commands.

320 The history command shows each tape that has a backup of the current
322 disk along with the date of the backup, the level, the tape label and
323 the file position on the tape. All active tapes are listed, not just
324 back to the most recent full dump.
325 Tape file position zero is a label. The first backup image is in file
327 position one.

348 PAGER The ls and list commands will use $PAGER to display the file
349 lists. Defaults to more if PAGER is not set.
350 AMANDA_SERVER If set, $AMANDA_SERVER will be used as index-server. The
352 value will take precedence over the compiled default, but will be
353 overridden by the -s switch.
354 AMANDA_TAPE_SERVER If set, $AMANDA_TAPE_SERVER will be used as
356 tape-server. The value will take precedence over the compiled default,
357 but will be overridden by the -t switch.
