NAME
duply - a shell frontend to duplicity for simplified backups
SYNOPSIS
duply profile create duply profile command [options ...] duply profile command[_command_...] [options ...]
DESCRIPTION
- 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.
USAGE
- 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).
PROFILE
- 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.
COMMANDS
usage Get usage help text.
create Creates a configuration profile.
- backup Backup with pre/post script execution (as batch the same as:
- pre_bkp_post)
- o as full backup if parameter full_if_older matches or no
earlier backup is found.
- o as incremental backup in all other cases.
- bkp As above but without executing pre/post scripts.
- full Force full backup.
- incr Force incremental backup.
- list [age]
- List all files in backup (as it was at age, default: now).
- status Prints backup sets and chains currently in repository.
- verify 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).
- pre/post
- execute the pre or post script of profile (for debugging purposes).
OPTIONS
- --force
- Passed to duplicity (see commands: purge, purge-full, cleanup).
- --preview
- Do nothing but print out generated duplicity command lines.
EXAMPLES
- 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
- 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).
IMPORTANT
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.
