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

331 Changes in release 2.4.1
333 * FAQ for new users, in docs/FAQ.
334 * A new `runspercycle' keyword in amanda.conf to specify the number
335 of amdump runs in a dumpcycle. The default is one run every day.
336 A value of 0 (the default) means the same value as dumpcycle.
337 A value of -1 means guess the number of runs from the tapelist file,
338 which is the number of tape used in the last dumpcycle days / runtapes.
339 If you don't run amdump every days, you must set runspercycle
340 otherwise amanda will noy be able to balance the dump. You must
341 set runspercycle to -1 if you want the same behavior as previous
343 * Space to be use as holding disk can now be "use all space except ??? Kb"
344 using a negative value for the 'use' parameter.
345 * amrecover will restore SAMBA backups using SAMBA.

353 * amlabel will only overwrite an Amanda tape if `-f' is specified.
354 * Tapes can now be marked so as not to be recycled with amadmin no-reuse.
355 * amidxtrm will no longer remove index files of backups in active tapes.
356 * Large dumps can now be split into multiple files on holding disk
357 (but they won't span across tapes yet).
358 * A total estimate time-out may be specified.
359 * Fixed skip-incr and skip-full support.
360 * amcheck now accepts -Maddress to send e-mail to the specified address.
361 * amdump, amflush and amcheck will use the log files as locks, so as
362 to avoid running concurrently.
363 * driver now supports configurable level-0 dumps in degraded mode via
364 new amanda.conf keyword "reserve"; see docs/WHATS.NEW for details.
365 * Configure now looks for vxdump and vxrestore in /usr/lib/fs/vxfs for Solaris
366 systems and will use it vxdump/vxrestore automatically on vxfs filesystems.
367 * New `killpgrp' setuid-root program, that kills estimate dumps even
368 if they are setuid-root.

385 a more portable and user-friendly format.
386 * Index files are now sent through a separate TCP connection, as they
387 are generated, instead of being stored in /tmp. This breaks Amanda
388 protocol backward compatibility.
389 * Estimates are now performed concurrently, if maxdumps>1.
390 * At configure time, it is now possible to specify a suffix for amanda
391 service names (--with-testing=suffix) and a directory for debugging
392 files (--with-debugging=/directory/name)
393 * New tape changer configuration keywords, that partially standardize
394 tape changer script configuration interface.

415 * Include the file seagate-changer.c which controls
416 Seagate/Conner/Archive autoloading DAT drive on NetBSD systems.
417 * Add a new amanda.conf option named "starttime" which is used in the
418 dumptype configuration. It takes one argument which is a time of day
419 (local timezone) formated as either hhmm or hmm (no `.'s, no `:'s,
420 just an integer). This tells Amanda to start a particular dump at
422 * Index files are now retrieved from the clients through amandad, not rsh/rcp.

437 and success or failure of those dumps over a complete tapecycle.
438 * Amanda now supports backups of clients in different domains. Requires
439 using the configure --with-fqdn options and fully qualified domain
440 names (FQDNs) in the disklist file.
441 * rth-changer checks all system calls for valid returns.
442 * no-changer and hp-changer use different status files and do more checking.

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

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