Script usage:
|
||||
|
||||
- Specify 'backup' or 'restore' mode:
|
||||
backup_and_restore.sh backup
|
||||
backup_and_restore.sh restore
|
||||
|
||||
- If you 'backup', you also have to specify what to backup.
|
||||
Use 'backup' to see the backup options you can use.
|
||||
|
||||
backup_and_restore.sh backup
|
||||
|
||||
The script also comes with support for environment variables.
|
||||
|
||||
Available environment variables:
|
||||
THREADS: Allows you to specify how many threads to backup with.
|
||||
example: THREADS=4 backup_and_restore.sh backup all
|
||||
|
||||
NODATE: Allows you to omit the date stamped folder.
|
||||
example: NODATE=1 backup_and_restore.sh backup all
|
||||
|
||||
IMPORTANT: If you'd like to restore a NODATE=1 backup, you have to
|
||||
use NODATE=1 for restoring as well! Otherwise, mailcow will only
|
||||
look for timestamped folders, which you will not have.
|
||||
|
||||
You can combine the variables as well.
|
||||
example: THREADS=4 NODATE=1 backup_and_restore.sh backup all
|
||||
|
||||
To do a full backup with the script, in an example "/backup/" folder:
|
||||
echo "/backup/" | backup_and_restore.sh backup all
|
||||
|
||||
To do a full backup with 4 threads:
|
||||
echo "/backup/" | THREADS=4 NODATE=1 backup_and_restore.sh backup all
|
||||
|
||||
To do a full backup with all available threads:
|
||||
echo "/backup/" | THREADS=\`getconf _NPROCESSORS_ONLN\` NODATE=1 backup_and_restore.sh backup all
