190 * Samba passwords are now sent to smbclient via a pipe and never displayed.
191 * Debug files in /tmp/amanda (--with-debug-dir) are now timestamped and old
192 ones automatically cleaned out. This means more space (a few KBytes) will
193 be used since in a given run, several of the programs are called more than
194 once. But it also means important debugging information should no longer
195 be lost by the file being overwritten. The length of time to keep the
196 files is controlled by --with-debug-days (default: 4). The old flag
197 --with-pid-debug-files is no longer needed and is ignored.
198 * dumptypes can be specialized in the disklist file
199 * Amanda will never use more space than specified (use) for an holding

221 Changes in release 2.4.1
223 * FAQ for new users, in docs/FAQ.
224 * A new `runspercycle' keyword in amanda.conf to specify the number
225 of amdump runs in a dumpcycle. The default is one run every day.
226 A value of 0 (the default) means the same value as dumpcycle.
227 A value of -1 means guess the number of runs from the tapelist file,
228 which is the number of tape used in the last dumpcycle days / runtapes.
229 If you don't run amdump every days, you must set runspercycle
230 otherwise amanda will noy be able to balance the dump. You must
231 set runspercycle to -1 if you want the same behavior as previous
233 * Space to be use as holding disk can now be "use all space except ??? Kb"
234 using a negative value for the 'use' parameter.
235 * amrecover will restore SAMBA backups using SAMBA.
236 * New `amstatus' program.

240 * ZFTAPEs are now supported on Linux.
241 * amrestore now accepts a list of filesystems to be restored.
242 * New `clean' amtape command.
243 * amlabel will only overwrite an Amanda tape if `-f' is specified.
244 * Tapes can now be marked so as not to be recycled with amadmin no-reuse.
245 * amidxtrm will no longer remove index files of backups in active tapes.
246 * Large dumps can now be split into multiple files on holding disk
247 (but they won't span across tapes yet).
248 * A total estimate time-out may be specified.
249 * Fixed skip-incr and skip-full support.
250 * amcheck now accepts -Maddress to send e-mail to the specified address.
251 * amdump, amflush and amcheck will use the log files as locks, so as
252 to avoid running concurrently.
253 * driver now supports configurable level-0 dumps in degraded mode via
254 new amanda.conf keyword "reserve"; see docs/WHATS.NEW for details.
255 * Configure now looks for vxdump and vxrestore in /usr/lib/fs/vxfs for Solaris
256 systems and will use it vxdump/vxrestore automatically on vxfs filesystems.
257 * New `killpgrp' setuid-root program, that kills estimate dumps even
258 if they are setuid-root.
260 Changes in release 2.4.0p1
262 * Fixed kerberos encryption
263 * New --with-owner configure option, to specify owner of installed files

274 * New text database format, to replace dbm/ndbm/gdbm/db databases with
275 a more portable and user-friendly format.
276 * Index files are now sent through a separate TCP connection, as they
277 are generated, instead of being stored in /tmp. This breaks Amanda
278 protocol backward compatibility.
279 * Estimates are now performed concurrently, if maxdumps>1.
280 * At configure time, it is now possible to specify a suffix for amanda
281 service names (--with-testing=suffix) and a directory for debugging
282 files (--with-debugging=/directory/name)
283 * New tape changer configuration keywords, that partially standardize
284 tape changer script configuration interface.
285 * amrecover can now handle GNU tar and AIX dump restores; it must now

300 commands. See examples/chg-generic.conf for more information.
301 * New configure options:
302 --with-db=DBLIB Force database library choice from {db,dbm,gdbm,ndbm}
303 --enable-buffered-dump Use buffered sockets on server for faster dumps
304 --with-group=GROUPNAME Install all files into group GROUPNAME
305 * Include the file seagate-changer.c which controls
306 Seagate/Conner/Archive autoloading DAT drive on NetBSD systems.
307 * Add a new amanda.conf option named "starttime" which is used in the
308 dumptype configuration. It takes one argument which is a time of day
309 (local timezone) formated as either hhmm or hmm (no `.'s, no `:'s,
310 just an integer). This tells Amanda to start a particular dump at
312 * Index files are now retrieved from the clients through amandad, not rsh/rcp.
313 * Fix configure bug when multiple invocations would not do the correct things.

327 and success or failure of those dumps over a complete tapecycle.
328 * Amanda now supports backups of clients in different domains. Requires
329 using the configure --with-fqdn options and fully qualified domain
330 names (FQDNs) in the disklist file.
331 * rth-changer checks all system calls for valid returns.
332 * no-changer and hp-changer use different status files and do more checking.
333 * amrestore works again with gzip compressed tapes.
334 * New setuid program rundump for systems where dump must run as root.
335 * Setuid programs are now installed o-rwx for tighter security.
336 * Fix bug where if Amanda was not configured using the --with-bsd-security
337 configure option, Amanda would not connect to the client machines. This
339 * Rundump and runtar now check if the proper user is invoking them.
340 * Amanda now can use gdbm if the compatibility header files are not installed.
341 * Bug fixes for gnutar file exclusions.

355 --with-mmap force mmap() instead of shared memory
356 --with-gnutar-listed-incremental=DIR gnutar directory lists go in DIR
357 --enable-gnutar-atime-preserve gnutar preserves atime, do not use
358 --with-pid-debug-files use pid in /tmp debugging filenames
359 * Samba support must now be explicitly included using --with-smblcient.
360 * Amanda now compiles with K&R compilers.
361 * Better AIX, Linux, OSF support.
362 * configure checks if /dev/r devices exist or not.

365 * Many bug fixes in the configure script for various platforms.
366 * Many bug fixes to codes.
368 Changes in release 2.3.0.4b1
369 * Configuration now uses configure. Build environment now uses
370 automake and autoconf.
371 * Samba PC client backup support added.
372 * New programs and scripts:
373 amrmtape: invalidate the contents of an existing backup tape
374 amverify: check Amanda tapes for gnutar driven backups.
375 hp-changer: script for a HP DAT changer.
376 no-changer: make a single tape appear like an infinite count tape stacker.
377 * New options added to programs:
378 amadmin: `amadmin <conf> version' shows version information.
379 amtape: `amtape <conf> current' shows the current tape label,
380 * Amanda now supports server side compression of dumps on the tape
381 host. Use the srvcompress option in amanda.conf.

407 * A number of material bugs fixed, including fixes incorporated into
408 John Stoffel's WPI patches to amanda, which he called 2.2.6.5.

410 2^31 Kbytes (2 terabytes), which should hold us for a few more years
412 * Support for GNUTAR-based backups.
413 * Support for writing to multiple tapes (sequentially) in one run.
414 * Support for multiple backups in parallel from the same client host.
415 * Records from the curinfo database can be exported and imported
416 to/from a textual format. This allows fixing a corrupted database by
417 running the text version through a script and reimporting it.
418 Individual records or the entire database can be exported/imported.

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

442 if you wish, and it won't get confused.
443 * Supports Kerberos 4 security as well as BSD-style .rhosts, including
444 encrypting files over the net. The Kerberos support is available as
445 a separate add-on package - see the file KERBEROS.HOW-TO-GET on the
447 * Improved network protocol - faster startup, no longer dump specific,
448 hooks in place for non-dump clients.
449 * Client-side checks in amcheck - can check sanity of all client hosts
