File and directory backup tool
positional arguments:
source Source directory to backup
destination Destination directory for backup
optional arguments:
-h, --help show this help message and exit
--backup-type {full,incremental}
Backup type: full or incremental
--method {rsync,shutil}
Backup method: rsync or shutil
--compress Compress data during transfer
--bandwidth-limit BANDWIDTH_LIMIT
Limit the bandwidth in KB/s
$ file_dir_backup /path/to/source /path/to/destination --backup-type full --method rsync --compress --bandwidth-limit 1000
# 全量同步示例:
#$ file_dir_backup /home/hujianli/test/ /home/hujianli/backup/ --backup-type full --method rsync --compress --bandwidth-limit 1000
# 或者
$ python -m file_dir_backup /path/to/source /path/to/destination --backup-type full --method rsync --compress --bandwidth-limit 1000
# 增量同步示例:
#$ python -m file_dir_backup /home/hujianli/test/ /home/hujianli/backup/ --backup-type incremental --method rsync --compress --bandwidth-limit 1000
使用配置文件
支持的配置文件查找规则:
- 环境变量
FILE_DIR_BACKUP_CONFIG ~/.file_dir_backup.cfg./etc/file_dir_backup.cfg/etc/file_dir_backup.cfg
配置文件格式,以/etc/file_dir_backup.cfg为示例:
[backup]
source = /home/hujianli/test
destination =/home/hujianli/backup
# 备份类型
backup_type = full
# 备份方法
method = rsync
# 是否传输过程中压缩数据
compress = true
# 传输限速
bandwidth_limit = 1000
Python 代码使用
from file_dir_backup import BackupManager
# 示例用法
backup_manager = BackupManager(
source="/path/to/source",
destination="/path/to/destination",
backup_type="full",
method="rsync"
)
backup_manager.backup()
