# SAP HANA Support
|
||
|
||
BackupX provides two SAP HANA backup modes. Pick whichever fits your operations workflow.
|
||
|
||
## Mode 1: hdbsql Runner (console-managed)
|
||
|
||
Create a SAP HANA backup task in the Web console. The backend invokes `hdbsql` to execute the backup. Use this when BackupX should own the schedule.
|
||
|
||
**Source configuration supports:**
|
||
|
||
| Field | Options | Description |
|
||
|-------|---------|-------------|
|
||
| Backup type | `data` / `log` | Data or log backup |
|
||
| Backup level | `full` / `incremental` / `differential` | Auto-disabled for log backups |
|
||
| Parallel channels | `1 ~ 32` | Multi-path SQL (`BACKUP DATA USING FILE ('c1', 'c2', ...)`) |
|
||
| Retry count | `1 ~ 10` | Exponential backoff (`5s × attempt²`) |
|
||
| Instance number | Optional | Inferred from port or specified manually |
|
||
|
||
## Mode 2: Backint Protocol Agent (HANA native)
|
||
|
||
BackupX ships a built-in Backint Agent. SAP HANA calls it via the native `BACKUP DATA USING BACKINT` syntax, and data is routed automatically to any BackupX storage target (S3 / OSS / COS / WebDAV / 70+ backends).
|
||
|
||
### 1. Parameter file
|
||
|
||
```ini title="/opt/backupx/backint_params.ini"
|
||
#STORAGE_TYPE = s3
|
||
#STORAGE_CONFIG_JSON = /opt/backupx/storage.json
|
||
#PARALLEL_FACTOR = 4
|
||
#COMPRESS = true
|
||
#KEY_PREFIX = hana-backup
|
||
#CATALOG_DB = /opt/backupx/backint_catalog.db
|
||
#LOG_FILE = /var/log/backupx/backint.log
|
||
```
|
||
|
||
### 2. Storage config (same schema as storage targets)
|
||
|
||
```json title="/opt/backupx/storage.json"
|
||
{
|
||
"endpoint": "https://s3.amazonaws.com",
|
||
"region": "us-east-1",
|
||
"bucket": "hana-prod",
|
||
"accessKeyId": "AKIA...",
|
||
"secretAccessKey": "..."
|
||
}
|
||
```
|
||
|
||
### 3. Create the hdbbackint symlink
|
||
|
||
```bash
|
||
ln -s /opt/backupx/backupx /usr/sap/<SID>/SYS/global/hdb/opt/hdbbackint
|
||
```
|
||
|
||
### 4. Enable Backint in HANA `global.ini`
|
||
|
||
```ini
|
||
[backup]
|
||
data_backup_using_backint = true
|
||
catalog_backup_using_backint = true
|
||
log_backup_using_backint = true
|
||
data_backup_parameter_file = /opt/backupx/backint_params.ini
|
||
log_backup_parameter_file = /opt/backupx/backint_params.ini
|
||
```
|
||
|
||
### 5. Manual CLI invocation (troubleshooting)
|
||
|
||
```bash
|
||
backupx backint -f backup -i input.txt -o output.txt -p backint_params.ini
|
||
backupx backint -f restore -i input.txt -o output.txt -p backint_params.ini
|
||
backupx backint -f inquire -i input.txt -o output.txt -p backint_params.ini
|
||
backupx backint -f delete -i input.txt -o output.txt -p backint_params.ini
|
||
```
|
||
|
||
The Backint Agent maintains an `EBID ↔ object-key` catalog in a local SQLite DB. All operations follow the SAP HANA Backint protocol (`#PIPE` / `#SAVED` / `#RESTORED` / `#BACKUP` / `#NOTFOUND` / `#DELETED` / `#ERROR`).
