前言
備份軟件已經是一個老生常談的話題了,今天,要和大家分享一個備份工具——restic。
Restic是一種快速、高效、免費和開源的備份應用程序,它通過AES-256加密保護你的數據,Restic 還利用重復數據刪除來幫助節省備份空間。此外,Restic 與大多數主要的雲提供商兼容,支持三大操作系統(Linux、macOS、Windows)和一些較小的操作系統(FreeBSD、OpenBSD)。
目前,Restic已經在Github上標星 14.6K,累計分支 999 個

首先,你可以從源代碼編譯restic或從發布頁面下載它。一旦安裝好restic,就可以開始備份:
$ restic init --repo /tmp/backup
enter password for new backend:
enter password again:
created restic backend 085b3c76b9 at /tmp/backup
Please note that knowledge of your password is required to access the repository.
Losing your password means that your data is irrecoverably lost.
並添加一些數據:
$ restic --repo /tmp/backup backup ~/work
enter password for repository:
scan [/home/user/work]
scanned 764 directories, 1816 files in 0:00

接下來,你可以restic restore用於恢復文件,要獲取所有備份快照的列表,可以使用以下的命令:
restic -r b2:bucketname:/ snapshots
例如:
$ restic -r b2:g534fbucket:/ snapshots
enter password for repository:
ID Date Host Tags Directory
----------------------------------------------------------------------
d864c465 2018-03-27 15:20:42 client /home/curt/Documents
如果你要恢復整個快照,就運行以下命令:
restic -r b2:bucketname:/ restore snapshotID --target restoreDirectory
例如:
$ restic -r b2:g534fbucket:/ restore d864c465 --target ~
enter password for repository:
restoring <Snapshot d864c465 of [/home/curt/Documents] at 2018-03-27 15:20:42.833131988 -0400 EDT by curt@client> to /home/curt
如果該目錄仍然存在於你的系統上,請確保為restoreDirectory指定不同的位置。例如:
restic -r b2:g534fbucket:/ restore d864c465 --target /tmp
要恢復單個文件,請運行如下命令:
$ restic -r b2:g534fbucket:/restore snapshotID --target restoreDirectory --include filename
例如:
$ restic -r b2:g534fbucket:/ restore d864c465 --target /tmp --include file1.txt
enter password for repository:
restoring <Snapshot d864c465 of [/home/curt/Documents] at 2018-03-27 15:20:42.833131988 -0400 EDT by curt@client
