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

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

362 * amidxtrm will no longer remove index files of backups in active tapes.
363 * Large dumps can now be split into multiple files on holding disk
364 (but they won't span across tapes yet).
365 * A total estimate time-out may be specified.
366 * Fixed skip-incr and skip-full support.
367 * amcheck now accepts -Maddress to send e-mail to the specified address.
368 * amdump, amflush and amcheck will use the log files as locks, so as
369 to avoid running concurrently.
370 * driver now supports configurable level-0 dumps in degraded mode via
371 new amanda.conf keyword "reserve"; see docs/WHATS.NEW for details.
372 * Configure now looks for vxdump and vxrestore in /usr/lib/fs/vxfs for Solaris
373 systems and will use it vxdump/vxrestore automatically on vxfs filesystems.
374 * New `killpgrp' setuid-root program, that kills estimate dumps even
375 if they are setuid-root.

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

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

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

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

474 --enable-gnutar-atime-preserve gnutar preserves atime, do not use
475 --with-pid-debug-files use pid in /tmp debugging filenames
476 * Samba support must now be explicitly included using --with-smblcient.
477 * Amanda now compiles with K&R compilers.

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