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

176 * A new `ctimeout' keyword in amanda.conf to replace the CHECK_TIMEOUT
177 constant in amcheck.c.

181 Changes in release 2.4.1
183 * FAQ for new users, in docs/FAQ.
184 * A new `runspercycle' keyword in amanda.conf to specify the number
185 of amdump runs in a dumpcycle. The default is one run every day.
186 A value of 0 (the default) means the same value as dumpcycle.
187 A value of -1 means guess the number of runs from the tapelist file,
188 which is the number of tape used in the last dumpcycle days / runtapes.
189 If you don't run amdump every days, you must set runspercycle
190 otherwise amanda will noy be able to balance the dump. You must
191 set runspercycle to -1 if you want the same behavior as previous
193 * Space to be use as holding disk can now be "use all space except ??? Kb"
194 using a negative value for the 'use' parameter.
195 * amrecover will restore SAMBA backups using SAMBA.
196 * New `amstatus' program.
197 * New `chg-scsi' tape changer program, that replaces `chg-chio' and uses

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

227 * Updated to libtool 1.2a
228 * Minor portability-related bugfixes.

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

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

286 * Include amoverview which creates a list of each disk dumped and the level
287 and success or failure of those dumps over a complete tapecycle.
288 * Amanda now supports backups of clients in different domains. Requires
289 using the configure --with-fqdn options and fully qualified domain
290 names (FQDNs) in the disklist file.
291 * rth-changer checks all system calls for valid returns.
292 * no-changer and hp-changer use different status files and do more checking.
293 * amrestore works again with gzip compressed tapes.
294 * New setuid program rundump for systems where dump must run as root.
295 * Setuid programs are now installed o-rwx for tighter security.
296 * Fix bug where if Amanda was not configured using the --with-bsd-security
297 configure option, Amanda would not connect to the client machines. This
299 * Rundump and runtar now check if the proper user is invoking them.
300 * Amanda now can use gdbm if the compatibility header files are not installed.
301 * Bug fixes for gnutar file exclusions.

315 --with-mmap force mmap() instead of shared memory
316 --with-gnutar-listed-incremental=DIR gnutar directory lists go in DIR
317 --enable-gnutar-atime-preserve gnutar preserves atime, do not use
318 --with-pid-debug-files use pid in /tmp debugging filenames
319 * Samba support must now be explicitly included using --with-smblcient.
320 * Amanda now compiles with K&R compilers.
321 * Better AIX, Linux, OSF support.
322 * configure checks if /dev/r devices exist or not.
323 * Amanda uses POSIX fcntl locking before flock or lockf locking if available.

325 * Many bug fixes in the configure script for various platforms.
326 * Many bug fixes to codes.
328 Changes in release 2.3.0.4b1
329 * Configuration now uses configure. Build environment now uses
330 automake and autoconf.
331 * Samba PC client backup support added.
332 * New programs and scripts:
333 amrmtape: invalidate the contents of an existing backup tape
334 amverify: check Amanda tapes for gnutar driven backups.
335 hp-changer: script for a HP DAT changer.
336 no-changer: make a single tape appear like an infinite count tape stacker.
337 * New options added to programs:
338 amadmin: `amadmin <conf> version' shows version information.
339 amtape: `amtape <conf> current' shows the current tape label,
340 * Amanda now supports server side compression of dumps on the tape
341 host. Use the srvcompress option in amanda.conf.

367 * A number of material bugs fixed, including fixes incorporated into
368 John Stoffel's WPI patches to amanda, which he called 2.2.6.5.
369 * Backup files larger than 2 GB now supported. The current limit is
370 2^31 Kbytes (2 terabytes), which should hold us for a few more years
372 * Support for GNUTAR-based backups.
373 * Support for writing to multiple tapes (sequentially) in one run.
374 * Support for multiple backups in parallel from the same client host.
375 * Records from the curinfo database can be exported and imported
376 to/from a textual format. This allows fixing a corrupted database by
377 running the text version through a script and reimporting it.
378 Individual records or the entire database can be exported/imported.

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

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