139 * Samba passwords are now sent to smbclient via a pipe and never displayed.
140 * Debug files in /tmp/amanda (--with-debug-dir) are now timestamped and old
141 ones automatically cleaned out. This means more space (a few KBytes) will
142 be used since in a given run, several of the programs are called more than
143 once. But it also means important debugging information should no longer
144 be lost by the file being overwritten. The length of time to keep the
145 files is controlled by --with-debug-days (default: 4). The old flag
146 --with-pid-debug-files is no longer needed and is ignored.

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

192 * amlabel will only overwrite an Amanda tape if `-f' is specified.
193 * Tapes can now be marked so as not to be recycled with amadmin no-reuse.
194 * amidxtrm will no longer remove index files of backups in active tapes.
195 * Large dumps can now be split into multiple files on holding disk
196 (but they won't span across tapes yet).
197 * A total estimate time-out may be specified.
198 * Fixed skip-incr and skip-full support.
199 * amcheck now accepts -Maddress to send e-mail to the specified address.
200 * amdump, amflush and amcheck will use the log files as locks, so as
201 to avoid running concurrently.
202 * driver now supports configurable level-0 dumps in degraded mode via
203 new amanda.conf keyword "reserve"; see docs/WHATS.NEW for details.
204 * Configure now looks for vxdump and vxrestore in /usr/lib/fs/vxfs for Solaris
205 systems and will use it vxdump/vxrestore automatically on vxfs filesystems.
206 * New `killpgrp' setuid-root program, that kills estimate dumps even
207 if they are setuid-root.
209 Changes in release 2.4.0p1
211 * Fixed kerberos encryption
212 * New --with-owner configure option, to specify owner of installed files

223 * New text database format, to replace dbm/ndbm/gdbm/db databases with
224 a more portable and user-friendly format.
225 * Index files are now sent through a separate TCP connection, as they
226 are generated, instead of being stored in /tmp. This breaks Amanda
227 protocol backward compatibility.
228 * Estimates are now performed concurrently, if maxdumps>1.
229 * At configure time, it is now possible to specify a suffix for amanda
230 service names (--with-testing=suffix) and a directory for debugging
231 files (--with-debugging=/directory/name)
232 * New tape changer configuration keywords, that partially standardize
233 tape changer script configuration interface.
234 * amrecover can now handle GNU tar and AIX dump restores; it must now

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

276 and success or failure of those dumps over a complete tapecycle.
277 * Amanda now supports backups of clients in different domains. Requires
278 using the configure --with-fqdn options and fully qualified domain
279 names (FQDNs) in the disklist file.
280 * rth-changer checks all system calls for valid returns.
281 * no-changer and hp-changer use different status files and do more checking.
282 * amrestore works again with gzip compressed tapes.
283 * New setuid program rundump for systems where dump must run as root.
284 * Setuid programs are now installed o-rwx for tighter security.
285 * Fix bug where if Amanda was not configured using the --with-bsd-security
286 configure option, Amanda would not connect to the client machines. This
288 * Rundump and runtar now check if the proper user is invoking them.
289 * Amanda now can use gdbm if the compatibility header files are not installed.
290 * Bug fixes for gnutar file exclusions.

305 --with-gnutar-listed-incremental=DIR gnutar directory lists go in DIR
306 --enable-gnutar-atime-preserve gnutar preserves atime, do not use
307 --with-pid-debug-files use pid in /tmp debugging filenames
308 * Samba support must now be explicitly included using --with-smblcient.
309 * Amanda now compiles with K&R compilers.
310 * Better AIX, Linux, OSF support.
311 * configure checks if /dev/r devices exist or not.

319 automake and autoconf.
320 * Samba PC client backup support added.
321 * New programs and scripts:
322 amrmtape: invalidate the contents of an existing backup tape
323 amverify: check Amanda tapes for gnutar driven backups.
324 hp-changer: script for a HP DAT changer.
325 no-changer: make a single tape appear like an infinite count tape stacker.
326 * New options added to programs:

379 I don't have any HP/UX machines locally to try it on, but I've
380 tracked patches submitted by Neal Becker <neal@ctd.comset.com>, so
381 I'm reasonably confident that 2.2.6 shouldn't be far from the mark on

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