145 them on the destination
146 o supports filtering dumps with the same syntax as amfetchdump
147 o a --fulls-only option skips all incremental dumps on the source
148 o an --export option tries to move tertiary volumes to import/export
150 o command-line syntax has changed incompatibly; see manpage or
152 * Rewritten and improved:
156 Release Notes for amanda-3.1.0
159 * The 'rawtapedev' keyword was removed, and the 'label_new_tapes' keyword
161 * New warnings for dangerous splitting configurations
164 We have many changers implementing the new changer API. The new changers are
165 faster, more reliable, and have many new features. One new features is that
166 the changer keeps track of which label is in which slot, allowing it to
167 locate a tape faster. But with some changers (new chg-multi or chg-robot
168 without a barcode), it doesn't get automaticaly notified if you change the
169 volume in a slot. In this case, you must notify the changer of it with the
170 'amtape <conf> update' command:
171 amtape DailySet1 update 3-8
172 amtape DailySet1 update 3-8=
173 amtape DailySet1 update 3=DailySet-003
174 See amanda-changers(7) for more information.
177 New Amanda devices - see amanda-devices(7) for more information.
180 The default amandapass file for the amsamba application is
181 $CONFIG_DIR/amandapass, but it is /etc/amandapass for program GNUTAR.
182 Don't forget to move the file if you switch to the amsamba application.
184 ampgsql, amsuntar, amraw
185 New applications to back up PostgreSQL databases, Solaris systems, and
186 raw device files, respectively.
189 Amtape's behavior has changed; see NEWS
192 Rewritten with new command-line interface; see NEWS
195 New --label and --properties options give more information about device
198 New, more natural command-line interface (try 'amreport $config')
201 Release Notes for amanda-2.6.1
203 amgtar, amstar, amsamba, amzfs-sendrecv
204 Three new programs implementing application-api.
205 Swithching from the program "GNUTAR" to the application "amgtar" have some
207 - amgtar use by default the gtar --atime-preserve=system option, you must
208 disable it if you gtar relase doesn't have that option.
209 - Can be configured to cross filesystem.
210 - Can be configured to not check the device number on newer gtar
211 (--no-check-device of gtar).
212 - You can configure error message from gtar you don't want to see in the
215 amzfs-snapshot, script-email
216 Two new scripts implementing script-api.
217 The 'zfs-snapshot' script must be used only with the 'amgtar' application.
220 New program to manipulate file in amanda archive format.
223 Application (perl utility functions for Applications)
224 Archive (Perl access to the amanda archive library)
225 Constants (perl access to build-time configuration values)
226 MainLoop (Perl interface to the Glib MainLoop)
227 Process (interface to process), used by amcleanup.
228 Script (perl utility functions for Scripts)
229 Tapelist (Manipulate the Amanda tapelist)
233 Release Notes for amanda-2.6.0
236 New program written entirely in perl, it replaces 'amverify' and
239 amcryptsimple, amgpgcrypt
240 New encryption plugins based on gpg.
242 amserverconfig, amaddclient
243 New Initial Amanda configuration tools, these tools make assumptions,
247 'amverify' and 'amveryfyrun' are deprecated -- use amcheckdump.
248 'amdd' and 'ammt' are also deprecated. If you have scripts that use
249 them, then you must rewrite them in perl using the new perl modules.
252 --disable-shared doesn't work because perl modules require shared library.
253 Instead, use --with-static-binaries to build staticailly linked binaries.
254 --with-amlibdir, libraries are now installed in $amlibdir
255 --without-amlibdir : amlibdir=$libdir
256 --with-amlibdir=yes : amlibdir=$libdir/amanda (default value)
257 --with-amlibdir=/path/to/libdir : amlibdir=/path/to/libdir
258 --with-amlibexecdir, internal programs are installed in $amlibexecdir
259 --without-amlibexecdir : amlibdir=$libexecdir
260 --with-amlibexecdir=yes : amlibdir=$libexecdir/amanda
262 --with-amlibexecdir=/path/to/libexecdir : amlibdir=/path/to/libexecdir
263 --with-amperldir, Where to install perl modules
264 --without-amperldir : amperldir=$amlibdir/perl
265 --with-amperldir=yes : amperldir= $(perl installsitelib)
267 --with-amperldir=/path/to/perldir : amperldir=/path/to/perldir
270 Libraries are installed in $amlibdir (previously $libdir)
271 Internal programs are installed in $amlibexecdir (previously $libexecdir)
272 You must change your inetd/xinetd config for the new amandad path.
273 The amandad path change affect rsh/ssh auth, amanda-2.6.0 installations
274 will need to add an 'amandad_path' parameter to configuration files in
275 order to talk to older versions of Amanda:
276 amanda-2.6.0 client -> amanda-2.5.2 or earlier server: add
277 'amandad_path "/usr/libexec/amandad"' (or the appropriate path) to
278 /etc/amanda/amanda-client.conf
279 amanda-2.5.2 or earlier client -> amanda-2.6.0 server: add
280 'amandad_path "/usr/libexec/amanda/amandad"' (or the appropriate path)
281 to /etc/amanda/amanda-client.conf
282 amanda-2.6.0 server -> amanda-2.5.2 or earlier client: add
283 'amandad_path "/usr/libexec/amandad"' (or the appropriate path) to the
285 amanda-2.5.2 or earlier server -> amanda-2.6.0 client: add
286 'amandad_path "/usr/libexec/amanda/amandad"' (or the appropriate path)
288 The amandates files is now $localstatedir/amanda/amandates, previously it
289 was /etc/amandates, this file must be created on all client.
292 It now defaults to 'yes'.
295 glib is required to compile and run amanda.
296 It is free and can be downloaded form http://www.gtk.org/download/
299 The Device API is a complete rewrite of all tape-access functionality.
300 To use the Device API, all devices must be specified by their full
301 name, e.g., tape:/dev/nst0. Existing functionality is now available
302 in the tape, file, and rait devices, and a new Amazon S3 backend named
303 's3' is also available.
306 Link directly to Amanda, to support writing Amanda applications in Perl
308 Changer (Execute changer scripts)
309 Cmdline (Parse command line argument)
310 Config (Parse config files)
312 Debug (Write to debug files)
313 Logfile (Parse log files)
314 Tapefile (Parse tapelist file)
315 Perl modules are installed in $amperldir
317 local security driver (auth)
318 Allows backups of the Amanda server without any need for network
319 configuration, and similarly allows amrecover to work on the Amanda
320 server without any network configuration.
323 Almost 200 unit tests are available, which should be run on an installed
324 copy of Amanda. See http://wiki.zmanda.com/index.php/Testing for more
327 flush-threshold-dumped, flush-threshold-scheduled, taperflush
328 These three config options allow to better fill your tapes.
329 They are what was known as the taperstart/taperflush feature.
332 Release Notes for amanda-2.5.2
336 IPv6 support is enabled by default if your OS support it, if your OS is
337 not working correctly with IPV6, you can disable it at configure time
338 with '--without-ipv6'.
342 This option is useful only if you configured amanda with a big
343 '--with-maxtapeblocksize' and your hardware can't works with big block
347 Release Notes for amanda-2.5.1
352 This new feature will record all dump with timestamp instead of datestamp,
353 it will allow to do many dump in a day and recover easily anyone of them.
355 If you use this features, you will not be able to downgrade to 2.5.0 or
358 see the usetimestamps section of 'man amanda.conf'
363 These are 2 new auth, they still use bsd authentification like bsd, but
366 bsdudp is like bsd, it use udp for connecting to client but it will use
367 only one tcp port for all data stream.
369 bsdtcp use tcp to connect the to client and it's the only network
370 connection use. It doesn't have the udp packet size limit, so you can
371 have an unlimited number of DLE for a single host.
373 amrecover use the security-api
375 amrecover now use the security-api, You don't need to configure an
376 amindexd and an amidxtaped services in your xinetd.
377 amindexd and amidxtaped will be launched by amandad like any other services.
378 You must do modification to your xinetd configuration and .amandahosts toi
379 allow connection to amindexd and amidxtaped.
381 new format of xinetd.d/amanda
383 amandad get in arguments the list of services it can launch, you must add
384 theses services in the server_args options.
386 new format of .amandahosts
388 You must append to each line the services this client can launch, the
