###### Path Options
|
||||
|
||||
| Parameter | Description | Default |
|
||||
| ------------------------------ | --------------------------------------------------------------------------- | ----------------------- |
|
||||
| `DEFAULT_SCRIPT_LOCATION_PRE` | Location on filesystem inside container to execute bash scripts pre backup | `/assets/scripts/pre/` |
|
||||

|
||||
###### Pre Backup
|
||||
|
||||
If you want to execute a custom script before a backup starts, you can drop bash scripts with the extension of `.sh` in the location defined in `DB01_SCRIPT_LOCATION_PRE`. See the following example to utilize:
|
||||
|
||||
```bash
|
||||
$ cat pre-script.sh
|
||||
##!/bin/bash
|
||||
|
||||
# #### Example Pre Script
|
||||
# #### $1=DBXX_TYPE (Type of Backup)
|
||||
# #### $2=DBXX_HOST (Backup Host)
|
||||
# #### $3=DBXX_NAME (Name of Database backed up
|
||||
# #### $4=BACKUP START TIME (Seconds since Epoch)
|
||||
# #### $5=BACKUP FILENAME (Filename)
|
||||
|
||||
echo "${1} Backup Starting on ${2} for ${3} at ${4}. Filename: ${5}"
|
||||
```
|
||||
|
||||
## script DBXX_TYPE DBXX_HOST DBXX_NAME STARTEPOCH BACKUP_FILENAME
|
||||
${f} "${backup_job_db_type}" "${backup_job_db_host}" "${backup_job_db_name}" "${backup_routines_start_time}" "${target}"
|
||||
|
||||
Outputs the following on the console:
|
||||
|
||||
`mysql Backup Starting on example-db for example at 1647370800. Filename: mysql_example_example-db_202200315-000000.sql.bz2
|
||||
|
||||
###### Post backup
|
||||
|
||||
If you want to execute a custom script at the end of a backup, you can drop bash scripts with the extension of `.sh` in the location defined in `DB01_SCRIPT_LOCATION_POST`. Also to support legacy users `/assets/custom-scripts` is also scanned and executed.See the following example to utilize:
|
||||
|
||||
```bash
|
||||
$ cat post-script.sh
|
||||
##!/bin/bash
|
||||
|
||||
# #### Example Post Script
|
||||
# #### $1=EXIT_CODE (After running backup routine)
|
||||
# #### $2=DBXX_TYPE (Type of Backup)
|
||||
# #### $3=DBXX_HOST (Backup Host)
|
||||
# #### #4=DBXX_NAME (Name of Database backed up
|
||||
# #### $5=BACKUP START TIME (Seconds since Epoch)
|
||||
# #### $6=BACKUP FINISH TIME (Seconds since Epoch)
|
||||
# #### $7=BACKUP TOTAL TIME (Seconds between Start and Finish)
|
||||
# #### $8=BACKUP FILENAME (Filename)
|
||||
# #### $9=BACKUP FILESIZE
|
||||
# #### $10=HASH (If CHECKSUM enabled)
|
||||
# #### $11=MOVE_EXIT_CODE
|
||||
|
||||
echo "${1} ${2} Backup Completed on ${3} for ${4} on ${5} ending ${6} for a duration of ${7} seconds. Filename: ${8} Size: ${9} bytes MD5: ${10}"
|
||||
```
|
||||
|
||||
## script EXIT_CODE DB_TYPE DB_HOST DB_NAME STARTEPOCH FINISHEPOCH DURATIONEPOCH BACKUP_FILENAME FILESIZE CHECKSUMVALUE
|
||||
${f} "${exit_code}" "${dbtype}" "${backup_job_db_host}" "${backup_job_db_name}" "${backup_routines_start_time}" "${backup_routines_finish_time}" "${backup_routines_total_time}" "${target}" "${FILESIZE}" "${checksum_value}" "${move_exit_code}
|
||||
|
||||
Outputs the following on the console:
|
||||
|
||||
`0 mysql Backup Completed on example-db for example on 1647370800 ending 1647370920 for a duration of 120 seconds. Filename: mysql_example_example-db_202200315-000000.sql.bz2 Size: 7795 bytes Hash: 952fbaafa30437494fdf3989a662cd40 0`
|
||||
|
||||
If you wish to change the size value from bytes to megabytes set environment variable `DB01_SIZE_VALUE=megabytes`
|
||||
|
||||
You must make your scripts executable otherwise there is an internal check that will skip trying to run it otherwise.
|
||||
If for some reason your filesystem or host is not detecting it right, use the environment variable `DB01_POST_SCRIPT_SKIP_X_VERIFY=TRUE` to bypass.
|
||||
|
||||
|
||||
#### Job Backup Options
|
||||
|
||||
If `DEFAULT_` variables are set and you do not wish for the settings to carry over into your jobs, you can set the appropriate environment variable with the value of `unset`.
|
||||
Otherwise, override them per backup job. Additional backup jobs can be scheduled by using `DB02_`,`DB03_`,`DB04_` ... prefixes. See [Specific Database Options](#specific-database-options) which may overrule this list.

###### Pre Backup
|
||||
|
||||
If you want to execute a custom script before a backup starts, you can drop bash scripts with the extension of `.sh` in the location defined in `DB01_SCRIPT_LOCATION_PRE`. See the following example to utilize:
|
||||
|
||||
```bash
|
||||
$ cat pre-script.sh
|
||||
##!/bin/bash
|
||||
|
||||
# #### Example Pre Script
|
||||
# #### $1=DB01_TYPE (Type of Backup)
|
||||
# #### $2=DB01_HOST (Backup Host)
|
||||
# #### $3=DB01_NAME (Name of Database backed up
|
||||
# #### $4=BACKUP START TIME (Seconds since Epoch)
|
||||
# #### $5=BACKUP FILENAME (Filename)
|
||||
|
||||
echo "${1} Backup Starting on ${2} for ${3} at ${4}. Filename: ${5}"
|
||||
```
|
||||
|
||||
## script DB01_TYPE DB01_HOST DB01_NAME STARTEPOCH BACKUP_FILENAME
|
||||
${f} "${backup_job_db_type}" "${backup_job_db_host}" "${backup_job_db_name}" "${backup_routines_start_time}" "${target}"
|
||||
|
||||
Outputs the following on the console:
|
||||
|
||||
`mysql Backup Starting on example-db for example at 1647370800. Filename: mysql_example_example-db_202200315-000000.sql.bz2
|
||||
|
||||
###### Post backup
|
||||
|
||||
If you want to execute a custom script at the end of a backup, you can drop bash scripts with the extension of `.sh` in the location defined in `DB01_SCRIPT_LOCATION_POST`. Also to support legacy users `/assets/custom-scripts` is also scanned and executed.See the following example to utilize:
|
||||
|
||||
```bash
|
||||
$ cat post-script.sh
|
||||
##!/bin/bash
|
||||
|
||||
# #### Example Post Script
|
||||
# #### $1=EXIT_CODE (After running backup routine)
|
||||
# #### $2=DB_TYPE (Type of Backup)
|
||||
# #### $3=DB_HOST (Backup Host)
|
||||
# #### #4=DB_NAME (Name of Database backed up
|
||||
# #### $5=BACKUP START TIME (Seconds since Epoch)
|
||||
# #### $6=BACKUP FINISH TIME (Seconds since Epoch)
|
||||
# #### $7=BACKUP TOTAL TIME (Seconds between Start and Finish)
|
||||
# #### $8=BACKUP FILENAME (Filename)
|
||||
# #### $9=BACKUP FILESIZE
|
||||
# #### $10=HASH (If CHECKSUM enabled)
|
||||
# #### $11=MOVE_EXIT_CODE
|
||||
|
||||
echo "${1} ${2} Backup Completed on ${3} for ${4} on ${5} ending ${6} for a duration of ${7} seconds. Filename: ${8} Size: ${9} bytes MD5: ${10}"
|
||||
```
|
||||
|
||||
## script EXIT_CODE DB_TYPE DB_HOST DB_NAME STARTEPOCH FINISHEPOCH DURATIONEPOCH BACKUP_FILENAME FILESIZE CHECKSUMVALUE
|
||||
${f} "${exit_code}" "${dbtype}" "${dbhost}" "${dbname}" "${backup_routines_start_time}" "${backup_routines_finish_time}" "${backup_routines_total_time}" "${target}" "${FILESIZE}" "${checksum_value}" "${move_exit_code}
|
||||
|
||||
Outputs the following on the console:
|
||||
|
||||
`0 mysql Backup Completed on example-db for example on 1647370800 ending 1647370920 for a duration of 120 seconds. Filename: mysql_example_example-db_202200315-000000.sql.bz2 Size: 7795 bytes Hash: 952fbaafa30437494fdf3989a662cd40 0`
|
||||
|
||||
If you wish to change the size value from bytes to megabytes set environment variable `DB01_SIZE_VALUE=megabytes`
|
||||
|
||||
You must make your scripts executable otherwise there is an internal check that will skip trying to run it otherwise.
|
||||
If for some reason your filesystem or host is not detecting it right, use the environment variable `DB01_POST_SCRIPT_SKIP_X_VERIFY=TRUE` to bypass.

|

- Recently there was a request to have the container work with Kubernetes cron scheduling. This can theoretically be accomplished by setting the container `MODE=MANUAL` and then setting `MANUAL_RUN_FOREVER=FALSE` - You would also want to disable a few features from the upstream base images specifically `CONTAINER_ENABLE_SCHEDULING` and `CONTAINER_ENABLE_MONITORING`. This should allow the container to start, execute a backup by executing and then exit cleanly. An alternative way to running the script is to execute `/etc/services.available/10-db-backup/run`.
|
||||
|
||||
### Manual Backups
|
||||
Manual Backups can be performed by entering the container and typing `backup-now`. This will execute all the backup tasks that are scheduled by means of the `BACKUPXX_` variables. Alternatively if you wanted to execute a job on its own you could simply type `backup01-now` (or whatever your number would be). There is no concurrency, and jobs will be executed sequentially.
