Not all changes are listed. Please check man pages.
- Support for multiple simultaneous writes to storage devices
- Can write to all available drives in parallel.
- Works only with the new changer API.
- Useful if two or more volumes are used in a single run.
- Dump direct to tape can be scheduled any time during the run, previously they were done sequentially after all dump to holding disk.
- Enabled with the new 'taper-parallel-write' configuration option. see amanda.conf(5)
- Support for LEOM in storage devices
- allows splitting without partial parts, saving space.
- much more efficient, since parts need not be cached on disk in most cases.
- new, simpler splitting commands in the tapetype section
- part-size, part-cache-type, part-cache-dir, part-cache-max-size. see amanda.conf(5)
- Amanda server configuration file changes amanda.conf(5)
- new configuration keyword:
- taper-parallel-write -- How many drive amanda can write to in parallel.
- deprecated configuration keywords:
- amrecover_do_fsf
- amrecover_check_label
- new configuration keyword:
- The CONFIG parameter to amidxtaped is now required; this means that versions of amrecover older than 2.4.3 will be unable to recover from servers running Amanda-3.2 and later.
- The new dumptype and global parameters 'recovery-limit' can be used to limit which hosts may recover from a particular DLE. See amanda.conf(5) and amanda-auth(7) for more information.
- Several old changers have been removed - these changers will work with Amanda for the forseeable future, but are no longer included in the distribution.
- chg-chio
- chg-chs
- chg-iomega
- chg-juke
- chg-mcutil
- chg-mtx
- chg-null (use the new "chg-null:")
- chg-rait (use the new "chg-rait:{dev1,dev2}")
- chg-rth
- chg-scsi-chio
- chg-scsi
- Several old changers have been removed - these changers will work with Amanda for the forseeable future, but are no longer included in the distribution.
- Amdump change amdump(8)
- new '--no-taper' option to start the run in degraded mode
- Amvault changes amvault(8)
- Supports assembling split parts on the source volume and re-splitting them on the destination
- Supports filtering dumps with the same syntax as amfetchdump
- --fulls-only option skips all incremental dumps on the source
- --export option tries to move tertiary volumes to import/export slots when completed
- incompatible command-line syntax changes; see amvault(8) or 'amvault --help'
- Rewritten and improved:
- amoverview amoverview(8)
- amcheckdump amcheckdump(8)
