duply - a shell frontend to duplicity for simplified backups


duply profile create

duply profile command [options ...]

duply profile command[_command_...] [options ...]


Duply deals as a wrapper for the mighty duplicity magic. It simplifies running duplicity with cron or on command line by:
  - keeping settings in profiles per backup job 
  - enabling batch actions eg. backup_verify_purge
  - executing pre/post scripts
  - precondition checking for flawless duplicity operation

For each backup job one configuration profile must be created. The profile folder will be stored under ~/.duply/<profile> (where '~' is the current users home directory).

Hint: If the folder /etc/duply exists the profiles for the super user root will be searched and created there.


First time usage (profile creation):
     duply <profile> create

General usage in single mode (see EXAMPLES):

     duply <profile> <command> [<options> ...]

General usage in batch mode joining commands with '_' (see EXAMPLES):

     duply <profile> <command1>_<command2>[_<command3>...] [<options> ...]

Non duply options are passed on to duplicity (see OPTIONS).


location for profiles

Indicated by a profile name i.e. sample, which is resolved to ~/.duply/sample ('~' expands to environment variable $HOME).

Superuser root can place profiles under /etc/duply if the folder is manually created before running duply.

ATTENTION: If /etc/duply/ is created, old profiles under /root/.duply/ have to be moved manually to the former or will cease to work.

using profiles

Usually only the profile name will be used:
     duply humbug backup

Alternatively a path might be used. This might be useful for quick testing, restoring or exotic locations. Shell expansion should work as usual:

     duply ~/.duply/humbug backup

ATTENTION: The path must contain at least one '/', e.g ./test instead of only test.


Get usage help text.
Creates a configuration profile.
Backup with pre/post script execution (as batch the same as: pre_bkp_post)
as full backup if parameter full_if_older matches or no earlier backup is found.
as incremental backup in all other cases.
As above but without executing pre/post scripts.
Force full backup.
Force incremental backup.
list [age]
List all files in backup (as it was at age, default: now).
Prints backup sets and chains currently in repository.
List files changed since latest backup.
purge [--force]
Shows outdated backup archives (older than $MAX_AGE). Option --force delete these files.
purge-full [--force]
Shows outdated backups (more than $MAX_FULL_BACKUPS), the number of recent full backups and associated incrementals to keep. Option --force delete these files.
cleanup [--force]
Shows broken backup archives (e.g. after unfinished run). Option --force delete these files.
restore target_path [age]
Restore the backup to target_path (as it was at age).
fetch src_path target_path [age]
Restore single file/folder from backup (as it was at age).
execute the pre or post script of profile (for debugging purposes).


Passed to duplicity (see commands: purge, purge-full, cleanup).
Do nothing but print out generated duplicity command lines.


Create profile 'humbug':
     duply humbug create

and then edit the resulting conf file of this profile.

Backup 'humbug' now:

     duply humbug backup

List available backup sets of profile 'humbug':

     duply humbug status

List and delete obsolete backup archives of 'humbug':

     duply humbug purge --force

Restore latest backup of 'humbug' to /mnt/restore:

     duply humbug restore /mnt/restore

Restore /etc/passwd of 'humbug' from 4 days ago to /root/pw:

     duply humbug fetch etc/passwd /root/pw 4D

See man duplicity, section TIME FORMATS for the time format.

A one line batch job on 'humbug' for cron execution:

     duply humbug backup_verify_purge --force


Files in the profile folder(~/.duply/<profile>):
   conf .......... main configuration file
   pre ........... executed before a backup
   post .......... executed after a backup
   gpgkey.*.asc .. exported GPG key file(s)
   exclude ....... a globbing list of included or excluded files/folders

The rules for the exclude file can be found in man duplicity, section FILE SELECTION).


Copy the whole profile folder after the first backup to a safe place. It contains everything needed to restore your backups. You will need it if you have to restore the backup from another system (e.g. after a system crash). Keep access to these files restricted as they contain all information (gpg data, ftp data) to access and modify your backups.

Repeat this step after all configuration changes. Some configuration options are crucial for restoration.
