126 be used since in a given run, several of the programs are called more than
127 once. But it also means important debugging information should no longer
128 be lost by the file being overwritten. The length of time to keep the
129 files is controlled by --with-debug-days (default: 4). The old flag
130 --with-pid-debug-files is no longer needed and is ignored.
131 * updated chg-zd-mtx.sh.in changer.
133 Changes in release 2.4.2p1
135 * Bugs fix release, the most annoying one is that amanda could retry

164 Changes in release 2.4.1
166 * FAQ for new users, in docs/FAQ.
167 * A new `runspercycle' keyword in amanda.conf to specify the number
168 of amdump runs in a dumpcycle. The default is one run every day.
169 A value of 0 (the default) means the same value as dumpcycle.
170 A value of -1 means guess the number of runs from the tapelist file,
171 which is the number of tape used in the last dumpcycle days / runtapes.
172 If you don't run amdump every days, you must set runspercycle
173 otherwise amanda will noy be able to balance the dump. You must
174 set runspercycle to -1 if you want the same behavior as previous
176 * Space to be use as holding disk can now be "use all space except ??? Kb"
177 using a negative value for the 'use' parameter.
178 * amrecover will restore SAMBA backups using SAMBA.
179 * New `amstatus' program.

182 * Reporter can now print tape labels.
183 * ZFTAPEs are now supported on Linux.
184 * amrestore now accepts a list of filesystems to be restored.

188 * amidxtrm will no longer remove index files of backups in active tapes.
189 * Large dumps can now be split into multiple files on holding disk

192 * Fixed skip-incr and skip-full support.
193 * amcheck now accepts -Maddress to send e-mail to the specified address.
194 * amdump, amflush and amcheck will use the log files as locks, so as
195 to avoid running concurrently.
196 * driver now supports configurable level-0 dumps in degraded mode via
197 new amanda.conf keyword "reserve"; see docs/WHATS.NEW for details.
198 * Configure now looks for vxdump and vxrestore in /usr/lib/fs/vxfs for Solaris
199 systems and will use it vxdump/vxrestore automatically on vxfs filesystems.
200 * New `killpgrp' setuid-root program, that kills estimate dumps even
201 if they are setuid-root.
203 Changes in release 2.4.0p1
205 * Fixed kerberos encryption
206 * New --with-owner configure option, to specify owner of installed files

217 * New text database format, to replace dbm/ndbm/gdbm/db databases with
218 a more portable and user-friendly format.
219 * Index files are now sent through a separate TCP connection, as they
220 are generated, instead of being stored in /tmp. This breaks Amanda
221 protocol backward compatibility.
222 * Estimates are now performed concurrently, if maxdumps>1.
223 * At configure time, it is now possible to specify a suffix for amanda
224 service names (--with-testing=suffix) and a directory for debugging
225 files (--with-debugging=/directory/name)
226 * New tape changer configuration keywords, that partially standardize
227 tape changer script configuration interface.

243 commands. See examples/chg-generic.conf for more information.
244 * New configure options:
245 --with-db=DBLIB Force database library choice from {db,dbm,gdbm,ndbm}
246 --enable-buffered-dump Use buffered sockets on server for faster dumps
247 --with-group=GROUPNAME Install all files into group GROUPNAME
248 * Include the file seagate-changer.c which controls
249 Seagate/Conner/Archive autoloading DAT drive on NetBSD systems.
250 * Add a new amanda.conf option named "starttime" which is used in the
251 dumptype configuration. It takes one argument which is a time of day
252 (local timezone) formated as either hhmm or hmm (no `.'s, no `:'s,
253 just an integer). This tells Amanda to start a particular dump at
255 * Index files are now retrieved from the clients through amandad, not rsh/rcp.

269 * Include amoverview which creates a list of each disk dumped and the level
270 and success or failure of those dumps over a complete tapecycle.
271 * Amanda now supports backups of clients in different domains. Requires
272 using the configure --with-fqdn options and fully qualified domain
273 names (FQDNs) in the disklist file.
274 * rth-changer checks all system calls for valid returns.
275 * no-changer and hp-changer use different status files and do more checking.
276 * amrestore works again with gzip compressed tapes.

278 * Setuid programs are now installed o-rwx for tighter security.
279 * Fix bug where if Amanda was not configured using the --with-bsd-security
280 configure option, Amanda would not connect to the client machines. This
282 * Rundump and runtar now check if the proper user is invoking them.
283 * Amanda now can use gdbm if the compatibility header files are not installed.
284 * Bug fixes for gnutar file exclusions.

298 --with-mmap force mmap() instead of shared memory
299 --with-gnutar-listed-incremental=DIR gnutar directory lists go in DIR
300 --enable-gnutar-atime-preserve gnutar preserves atime, do not use
301 --with-pid-debug-files use pid in /tmp debugging filenames
302 * Samba support must now be explicitly included using --with-smblcient.
303 * Amanda now compiles with K&R compilers.
304 * Better AIX, Linux, OSF support.
305 * configure checks if /dev/r devices exist or not.

314 * Samba PC client backup support added.
315 * New programs and scripts:
316 amrmtape: invalidate the contents of an existing backup tape
317 amverify: check Amanda tapes for gnutar driven backups.
318 hp-changer: script for a HP DAT changer.
319 no-changer: make a single tape appear like an infinite count tape stacker.
320 * New options added to programs:
321 amadmin: `amadmin <conf> version' shows version information.
322 amtape: `amtape <conf> current' shows the current tape label,
323 * Amanda now supports server side compression of dumps on the tape
324 host. Use the srvcompress option in amanda.conf.

350 * A number of material bugs fixed, including fixes incorporated into
351 John Stoffel's WPI patches to amanda, which he called 2.2.6.5.
352 * Backup files larger than 2 GB now supported. The current limit is
353 2^31 Kbytes (2 terabytes), which should hold us for a few more years
355 * Support for GNUTAR-based backups.

357 * Support for multiple backups in parallel from the same client host.
358 * Records from the curinfo database can be exported and imported
359 to/from a textual format. This allows fixing a corrupted database by
360 running the text version through a script and reimporting it.
361 Individual records or the entire database can be exported/imported.

372 DEC OSF/1 2.0 AIX 3.2
373 I don't have any HP/UX machines locally to try it on, but I've
374 tracked patches submitted by Neal Becker <neal@ctd.comset.com>, so
375 I'm reasonably confident that 2.2.6 shouldn't be far from the mark on

384 * Amanda now thinks in real-time - you may run it several times a day
385 if you wish, and it won't get confused.
386 * Supports Kerberos 4 security as well as BSD-style .rhosts, including
387 encrypting files over the net. The Kerberos support is available as
388 a separate add-on package - see the file KERBEROS.HOW-TO-GET on the
390 * Improved network protocol - faster startup, no longer dump specific,
391 hooks in place for non-dump clients.
392 * Client-side checks in amcheck - can check sanity of all client hosts
