Description: `
|
|
||||||
Run an app backup.
|
|
||||||
|
|
||||||
A backup command and pre/post hook commands are defined in the recipe
|
|
||||||
configuration. Abra reads this configuration and run the comands in the context
|
|
||||||
of the deployed services. Pass <service> if you only want to back up a single
|
|
||||||
service. All backups are placed in the ~/.abra/backups directory.
|
|
||||||
|
|
||||||
A single backup file is produced for all backup paths specified for a service.
|
|
||||||
If we have the following backup configuration:
|
|
||||||
|
|
||||||
- "backupbot.backup.path=/var/lib/foo,/var/lib/bar"
|
|
||||||
|
|
||||||
And we run "abra app backup example.com app", Abra will produce a file that
|
|
||||||
looks like:
|
|
||||||
|
|
||||||
~/.abra/backups/example_com_app_609341138.tar.gz
|
|
||||||
|
|
||||||
This file is a compressed archive which contains all backup paths. To see paths, run:
|
|
||||||
|
|
||||||
tar -tf ~/.abra/backups/example_com_app_609341138.tar.gz
|
|
||||||
|
|
||||||
(Make sure to change the name of the backup file)
|
|
||||||
|
|
||||||
This single file can be used to restore your app. See "abra app restore" for more.

Description: `
|
|
||||||
Run an app restore.
|
|
||||||
|
|
||||||
Pre/post hook commands are defined in the recipe configuration. Abra reads this
|
|
||||||
configuration and run the comands in the context of the service before
|
|
||||||
restoring the backup.
|
|
||||||
|
|
||||||
Unlike "abra app backup", restore must be run on a per-service basis. You can
|
|
||||||
not restore all services in one go. Backup files produced by Abra are
|
|
||||||
compressed archives which use absolute paths. This allows Abra to restore
|
|
||||||
according to standard tar command logic, i.e. the backup will be restored to
|
|
||||||
the path it was originally backed up from.
|
|
||||||
|
|
||||||
Example:
|
|
||||||
|
|
||||||
abra app restore example.com app ~/.abra/backups/example_com_app_609341138.tar.gz
