341 be used since in a given run, several of the programs are called more than
342 once. But it also means important debugging information should no longer
343 be lost by the file being overwritten. The length of time to keep the
344 files is controlled by --with-debug-days (default: 4). The old flag

372 * A new `runspercycle' keyword in amanda.conf to specify the number
373 of amdump runs in a dumpcycle. The default is one run every day.
374 A value of 0 (the default) means the same value as dumpcycle.
375 A value of -1 means guess the number of runs from the tapelist file,
376 which is the number of tape used in the last dumpcycle days / runtapes.
377 If you don't run amdump every days, you must set runspercycle
378 otherwise amanda will noy be able to balance the dump. You must
379 set runspercycle to -1 if you want the same behavior as previous
381 * Space to be use as holding disk can now be "use all space except ??? Kb"
382 using a negative value for the 'use' parameter.
383 * amrecover will restore SAMBA backups using SAMBA.

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

423 a more portable and user-friendly format.
424 * Index files are now sent through a separate TCP connection, as they
425 are generated, instead of being stored in /tmp. This breaks Amanda
426 protocol backward compatibility.
427 * Estimates are now performed concurrently, if maxdumps>1.
428 * At configure time, it is now possible to specify a suffix for amanda
429 service names (--with-testing=suffix) and a directory for debugging
430 files (--with-debugging=/directory/name)
431 * New tape changer configuration keywords, that partially standardize
432 tape changer script configuration interface.

453 * Include the file seagate-changer.c which controls
454 Seagate/Conner/Archive autoloading DAT drive on NetBSD systems.
455 * Add a new amanda.conf option named "starttime" which is used in the
456 dumptype configuration. It takes one argument which is a time of day
457 (local timezone) formated as either hhmm or hmm (no `.'s, no `:'s,
458 just an integer). This tells Amanda to start a particular dump at

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