4 # duply (grown out of ftplicity), is a shell front end to duplicity that #
5 # simplifies the usage by managing settings for backup jobs in profiles. #
6 # It supports executing multiple commands in a batch mode to enable single #
7 # line cron entries and executes pre/post backup scripts. #
8 # Since version 1.5.0 all duplicity backends are supported. Hence the name #
9 # changed from ftplicity to duply. #
10 # See http://duply.net or http://ftplicity.sourceforge.net/ for more info. #

134 # that should only come w/ a major version change. so, here we go ;)
135 # if your backend stops working w/ this version create a new profile and
136 # export the env vars needed as described in the comments of the conf file
137 # directly above the SOURCE setting.
138 # Changes:
139 # - making sure multi spaces in TARGET survive awk processing
140 # - new env var PROFILE exported to scripts
141 # - fix 102: expose a unique timestamp variable for pre/post scripts
142 # actually a featreq. exporting RUN_START nanosec unix timestamp
143 # - fix 101: GPG_AGENT_INFO is 'bogus' (thx Thomas Harning Jr.)
144 # - fix 96: duply cannot handle two consecutive spaces in paths
145 #

161 # - add PYTHON conf var to allow global override of used python interpreter
162 # - enforced usage of "python2" in PATH as default interpreter for internal

180 # - implemented base-/dirname as bash functions

182 # contributed patch by Scott McKenzie and instead opted for removing almost

185 # feature. the future alternative for users is to consult the duplicity

419 #
420 # 1.5.0 (01.07.2009)
421 # - removed ftp limitation, all duplicity backends should work now
422 # - bugfix: date for separator failed on openwrt busybox date, added a
423 # detecting workaround, milliseconds are not available w/ busybox date
424 #
425 # 1.4.2.1 (14.05.2009)
426 # - bugfix: free temp space detection failed with lvm, fixed awk parse routine
427 #
428 # 1.4.2 (22.04.2009)
429 # - gpg keys are now exported as gpgkey.[id].asc , the suffix reflects the
430 # armored ascii nature, the id helps if the key is switched for some reason
431 # im/export routines are updated accordingly (import is backward compatible
432 # to the old profile/gpgkey files)
433 # - profile argument is treated as path if it contains slashes
434 # (for details see usage)
435 # - non-ftplicity options (all but --preview currently) are now passed
436 # on to duplicity
437 # - removed need for stat in secure_conf, it is ls based now
438 # - added profile folder readable check
439 # - added gpg version & home info output
440 # - awk utility availability is now checked, because it was mandatory already
441 # - tmp space is now checked on writability and space requirement
442 # test fails on less than 25MB or configured $VOLSIZE,
443 # test warns if there is less than two times $VOLSIZE because
444 # that's required for --asynchronous-upload option
445 # - gpg functionality is tested now before executing duplicity
446 # test drive contains encryption, decryption, comparison, cleanup
447 # this is meant to detect non trusted or other gpg errors early
448 # - added possibility of doing symmetric encryption with duplicity
449 # set GPG_KEY="" or simply comment it out
450 # - added hints in config template on the depreciation of
451 # --short-filenames, --time-separator duplicity options
452 #
453 # new versioning scheme 1.4.2b => 1.4.2,
454 # beta b's are replaced by a patch count number e.g. 1.4.2.1 will be assigned
455 # to the first bug fixing version and 1.4.2.2 to the second and so on
456 # also the releases will now have a release date formatted (Day.Month.Year)
457 #
458 # 1.4.1b1 - bugfix: ftplicity changed filesystem permission of a folder
459 # named exactly as the profile if existing in executing dir
460 # - improved plausibility checking of config and profile folder
461 # - secure_conf only acts if needed and prints a warning now
462 #
463 # 1.4.1b - introduce status (duplicity collection-status) command
464 # - pre/post script output printed always now, not only on errors
465 # - new config parameter GPG_OPTS to pass gpg options
466 # added examples & comments to profile template conf
467 # - reworked separator times, added duration display
468 # - added --preview switch, to preview generated command lines
469 # - disabled MAX_AGE, MAX_FULL_BACKUPS, VERBOSITY in generated
470 # profiles because they have reasonable defaults now if not set
471 #
472 # 1.4.0b1 - bugfix: incr forces incremental backups on duplicity,
473 # therefore backup translates to pre_bkp_post now
474 # - bugfix: new command bkp, which represents duplicity's
475 # default action (incr or full if full_if_older matches
476 # or no earlier backup chain is found)
477 #
478 # new versioning scheme 1.4 => 1.4.0, added new minor revision number
479 # this is meant to slow down the rapid version growing but still keep
480 # versions cleanly separated.
481 # only additional features will raise the new minor revision number.
482 # all releases start as beta, each bugfix release will raise the beta
483 # count, usually new features arrive before a version 'ripes' to stable
484 #
485 # 1.4.0b
486 # 1.4b - added startup info on version, time, selected profile
487 # - added time output to separation lines
488 # - introduced: command purge-full implements duplicity's
489 # remove-all-but-n-full functionality (patch by unknown),
490 # uses config variable $MAX_FULL_BACKUPS (default = 1)
491 # - purge config var $MAX_AGE defaults to 1M (month) now
492 # - command full does not execute pre/post anymore
493 # use batch command pre_full_post if needed
494 # - introduced batch mode cmd1_cmd2_etc
495 # (in turn removed the bvp command)
496 # - unknown/undefined command issues a warning/error now
497 # - bugfix: version check works with 0.4.2 and older now
498 # 1.3b3 - introduced pre/post commands to execute/debug scripts
499 # - introduced bvp (backup, verify, purge)
500 # - bugfix: removed need for awk gensub, now mawk compatible
501 # 1.3b2 - removed pre/post need executable bit set
502 # - profiles now under ~/.ftplicity as folders
503 # - root can keep profiles in /etc/ftplicity, folder must be
504 # created by hand, existing profiles must be moved there
505 # - removed ftplicity in path requirement
506 # - bugfix: bash < v.3 did not know '=~'
507 # - bugfix: purge works again
508 # 1.3 - introduces multiple profiles support
509 # - modified some script errors/docs
510 # - reordered gpg key check import routine
511 # - added 'gpg key id not set' check
512 # - added error_gpg (adds how to setup gpg key howto)
513 # - bugfix: duplicity 0.4.4RC4+ parameter syntax changed
514 # - duplicity_version_check routine introduced
515 # - added time separator, shortnames, volsize, full_if_older

673 VERSION:
674 $(version_info)
675
676 DESCRIPTION:
677 Duply deals as a wrapper for the mighty duplicity magic.
678 It simplifies running duplicity with cron or on command line by:
679
680 - keeping recurring settings in profiles per backup job
681 - enabling batch operations e.g. backup_verify+purge
682 - executing pre/post scripts (different actions possible
683 depending on previous or next command or it's exit status)
684 - precondition checking for flawless duplicity operation
685
686 For each backup job one configuration profile must be created.
687 The profile folder will be stored under '~/.${ME_NAME}/<profile>'
688 (where ~ is the current users home directory).
689 Hint:
690 If the folder '/etc/${ME_NAME}' exists, the profiles for the super
691 user root will be searched & created there.
692
693 USAGE:
694 first time usage (profile creation):
695 $ME <profile> create
696
697 general usage in single or batch mode (see EXAMPLES):
698 $ME <profile> <command>[[_|+|-]<command>[_|+|-]...] [<options> ...]
699
700 For batches the conditional separators can also be written as pseudo commands
701 and(+), or(-). See SEPARATORS for details.
702
703 Non $ME options are passed on to duplicity (see OPTIONS).
704 All conf parameters can also be defined in the environment instead.
705
706 PROFILE:
707 Indicated by a path or a profile name (<profile>), which is resolved
708 to '~/.${ME_NAME}/<profile>' (~ expands to environment variable \$HOME).
709
710 Superuser root can place profiles under '/etc/${ME_NAME}'. Simply create
711 the folder manually before running $ME_NAME as superuser.
712 Note:
713 Already existing profiles in root's home folder will cease to work
714 unless they are moved to the new location manually.
715
716 example 1: $ME humbug backup
717
718 Alternatively a _path_ might be used e.g. useful for quick testing,
719 restoring or exotic locations. Shell expansion should work as usual.
720 Hint:
721 The path must contain at least one path separator '/',
722 e.g. './test' instead of only 'test'.
723
724 example 2: $ME ~/.${ME_NAME}/humbug backup
725
726 SEPARATORS:
727 _ (underscore)
728 neutral separator
729 + (plus sign), _and_
730 conditional AND
731 the next command will only be executed if the previous succeeded
732 - (minus sign), _or_
733 conditional OR
734 the next command will only be executed if the previous failed
735 [] (square brackets), _groupIn_/_groupOut_
736 enables grouping of commands
737
738 example:
739 'pre+[bkp-verify]_post' translates to
740 'pre_and_groupIn_bkp_or_verify_groupOut_post'
741
742 COMMANDS:
743 usage get usage help text
744
745 and/or/groupIn/groupOut
746 pseudo commands used in batches (see SEPARATORS above)
747
748 create creates a configuration profile
749 backup backup with pre/post script execution (batch: [pre_bkp_post]),
750 full (if full_if_older matches or no earlier backup is found)
751 incremental (in all other cases)
752 pre/post execute '<profile>/$(basename "$PRE")', '<profile>/$(basename "$POST")' scripts
753 bkp as above but without executing pre/post scripts
754 full force full backup
755 incr force incremental backup
756 list [<age>]
757 list all files in backup (as it was at <age>, default: now)
758 status prints backup sets and chains currently in repository
759 verify [<age>] [--compare-data]
760 list files changed, since age if given
761 verifyPath <rel_path_in_bkp> <local_path> [<age>] [--compare-data]
762 list changes of a file or folder path in backup compared to a
763 local path, since age if given
764 restore <target_path> [<age>]
765 restore the complete backup to <target_path> [as it was at <age>]
766 fetch <src_path> <target_path> [<age>]
767 fetch single file/folder from backup [as it was at <age>]
768 purge [<max_age>] [--force]
769 list outdated backup files (older than \$MAX_AGE)
770 [use --force to actually delete these files]
771 purgeFull [<max_full_backups>] [--force]
772 list outdated backup files (\$MAX_FULL_BACKUPS being the number of
773 full backups and associated incrementals to keep, counting in
774 reverse chronological order)
775 [use --force to actually delete these files]
776 purgeIncr [<max_fulls_with_incrs>] [--force]
777 list outdated incremental backups (\$MAX_FULLS_WITH_INCRS being
778 the number of full backups which associated incrementals will be
779 kept, counting in reverse chronological order)
780 [use --force to actually delete these files]
781 purgeAuto [--force]
782 convenience batch wrapper for all purge commands above.
783 purge, purgeFull, purgeIncr are added if their conf vars were set. e.g.
784 MAX_AGE=1Y
785 MAX_FULL_BACKUPS=6
786 MAX_FULLS_WITH_INCR=3
787 in profile conf file would result in
788 [purge_purgeFull_purgeIncr]
789 cleanup [--force]
790 list broken backup chain files archives (e.g. after unfinished run)
791 [use --force to actually delete these files]

794 txt2man feature for package maintainers - create a manpage based on the
795 usage output. download txt2man from http://mvertes.free.fr/, put
796 it in the PATH and run '$ME txt2man' to create a man page.
797 version show version information of $ME_NAME and needed programs
798
799 OPTIONS:
800 --force passed to duplicity (see commands:
801 purge, purgeFull, purgeIncr, cleanup)
802 --preview do nothing but print out generated duplicity command lines
803 --disable-encryption
804 disable encryption, overrides profile settings
805
806 TIME FORMATS:
807 For all time related parameters like age, max_age etc.
808 Refer to the duplicity manpage for all available formats. Here some examples:
809 2002-01-25T07:00:00+02:00 (full date time format string)
810 2002/3/5 (date string YYYY/MM/DD)
811 12D (interval, 12 days ago)
812 1h78m (interval, 1 hour 78 minutes ago)
813
814 PRE/POST SCRIPTS:
815 Some useful internal duply variables are exported to the scripts.
816
817 PROFILE, CONFDIR, SOURCE, TARGET_URL_<PROT|HOSTPATH|USER|PASS>,
818 GPG_<KEYS_ENC|KEY_SIGN|PW>, CMD_ERR, RUN_START,
819 CMD_<PREV|NEXT> (previous/next command),
820 CND_<PREV|NEXT> (condition before/after)
821
822 The CMD_* variables were introduced to allow different actions according to
823 the command the scripts were attached to e.g. 'pre_bkp_post_pre_verify_post'
824 will call the pre script two times, with CMD_NEXT variable set to 'bkp'
825 on the first and to 'verify' on the second run.
826 CMD_ERR holds the exit code of the CMD_PREV .
827
828 EXAMPLES:
829 create profile 'humbug':
830 $ME humbug create (don't forget to edit this new conf file)
831 backup 'humbug' now:
832 $ME humbug backup
833 list available backup sets of profile 'humbug':
834 $ME humbug status
835 list and delete outdated backups of 'humbug':
836 $ME humbug purge --force
837 restore latest backup of 'humbug' to /mnt/restore:
838 $ME humbug restore /mnt/restore
839 restore /etc/passwd of 'humbug' from 4 days ago to /root/pw:
840 $ME humbug fetch etc/passwd /root/pw 4D
841 (see "duplicity manpage", section TIME FORMATS)
842 a one line batch job on 'humbug' for cron execution:
843 $ME humbug backup_verify_purge --force
844 batch job to run a full backup with pre/post scripts:
845 $ME humbug pre_full_post
846
847 FILES:
848 in profile folder '~/.${ME_NAME}/<profile>' or '/etc/${ME_NAME}'
849 conf profile configuration file
850 pre,post pre/post scripts (see above for details)

1085 IMPORTANT:
1086 Copy the _whole_ profile folder after the first backup to a safe place.
1087 It contains everything (duply related) needed to restore your backups.
1088
1089 Pay attention to (possibly later added) external files such as credentials
1090 or auth files (e.g. netrc, .megarc, ssh keys) or environment variables
1091 (e.g. DPBX_ACCESS_TOKEN).
1092 It is good policy to place those in the profile folder if possible at all.
1093 e.g. in case of 'multi://' target the config .json file
1094 Env vars should be added to duply profiles' conf file.
1095
1096 Keep access to these files restricted as they contain information (gpg key,
1097 passphrases etc.) to access and modify your backups.
1098
1099 Finally:
1100 You should attempt a restore from an unrelated host to be sure you really
1101 have everything needed for restoration.
1102
1103 Repeat these steps after _all_ configuration changes. Some configuration
1104 options are crucial for restoration.
