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

384 * A new `runspercycle' keyword in amanda.conf to specify the number
385 of amdump runs in a dumpcycle. The default is one run every day.
386 A value of 0 (the default) means the same value as dumpcycle.
387 A value of -1 means guess the number of runs from the tapelist file,
388 which is the number of tape used in the last dumpcycle days / runtapes.
389 If you don't run amdump every days, you must set runspercycle
390 otherwise amanda will noy be able to balance the dump. You must
391 set runspercycle to -1 if you want the same behavior as previous
393 * Space to be use as holding disk can now be "use all space except ??? Kb"
394 using a negative value for the 'use' parameter.
395 * amrecover will restore SAMBA backups using SAMBA.

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

435 a more portable and user-friendly format.
436 * Index files are now sent through a separate TCP connection, as they
437 are generated, instead of being stored in /tmp. This breaks Amanda
438 protocol backward compatibility.
439 * Estimates are now performed concurrently, if maxdumps>1.
440 * At configure time, it is now possible to specify a suffix for amanda
441 service names (--with-testing=suffix) and a directory for debugging
442 files (--with-debugging=/directory/name)
443 * New tape changer configuration keywords, that partially standardize
444 tape changer script configuration interface.

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

487 and success or failure of those dumps over a complete tapecycle.
488 * Amanda now supports backups of clients in different domains. Requires
489 using the configure --with-fqdn options and fully qualified domain
490 names (FQDNs) in the disklist file.

492 * no-changer and hp-changer use different status files and do more checking.

573 * Support for writing to multiple tapes (sequentially) in one run.
574 * Support for multiple backups in parallel from the same client host.
575 * Records from the curinfo database can be exported and imported
576 to/from a textual format. This allows fixing a corrupted database by
577 running the text version through a script and reimporting it.
578 Individual records or the entire database can be exported/imported.
580 Changes in release 2.2.6
581 * A number of material bugs fixed.
582 * A lot of lint picked in the whole package.
583 * The documentation is now reasonably up to date.
584 * This version has been locally compiled and at least the client side
585 tested on the following systems:
587 Solaris 2.3 BSDI BSD/386 1.1
588 Ultrix 4.2 NetBSD 1.0
589 DEC OSF/1 2.0 AIX 3.2
590 I don't have any HP/UX machines locally to try it on, but I've
591 tracked patches submitted by Neal Becker <neal@ctd.comset.com>, so
592 I'm reasonably confident that 2.2.6 shouldn't be far from the mark on
595 Changes in release 2.2.5
596 * SYSV shared memory no longer required on server side if mmap is
598 * Supports GZIP compression.
599 * Supports use of mount names as well as device names in disk list
600 (eg "/usr" instead of "sd0g").
601 * Amanda now thinks in real-time - you may run it several times a day
602 if you wish, and it won't get confused.
603 * Supports Kerberos 4 security as well as BSD-style .rhosts, including
604 encrypting files over the net. The Kerberos support is available as
605 a separate add-on package - see the file KERBEROS.HOW-TO-GET on the
607 * Improved network protocol - faster startup, no longer dump specific,
608 hooks in place for non-dump clients.
609 * Client-side checks in amcheck - can check sanity of all client hosts
611 * Supports multiple holding disks, and load balances between them.
