Attic是一个deduplicating备份程序。Attic的主要目的是提供一种有效和安全的方式来备份数据。使用重复数据删除技术使得Attic适合日常备份，因为只存储有更改的部分。
易于使用
初始化备份库，并创建一个备份存档：
$ attic init /usbdrive/my-backup.attic $ attic create -v /usbdrive/my-backup.attic::documents ~/Documents
主要特性：
- Space efficient storage
- Variable block size deduplication is used to reduce the number of bytes stored by detecting redundant data. Each file is split into a number of variable length chunks and only chunks that have never been seen before are compressed and added to the repository.
- Optional data encryption
- All data can be protected using 256-bit AES encryption and data integrity and authenticity is verified using HMAC-SHA256.
- Off-site backups
- Attic can store data on any remote host accessible over SSH. This is most efficient if Attic is also installed on the remote host.
- Backups mountable as filesystems
- Backup archives are mountable as userspace filesystems for easy backup verification and restores.
