Here is how to create a simple borg backup. Something more along the lines of a zip file than a careful backup system. I’m using this method for long term storage. The primary benefits are de-duplication and compression.<\/p>\n\n\n\n
Again, to clarify – these are not backups meant to be updated each day\/week\/month. These are simply long term storage that I normally would have made by rsyncing or making a tgz.<\/p>\n\n\n\n
To create, run the following (see below for encrypted backup option):<\/p>\n\n\n\n
# create an empty archive called test1\nborg init -e none test1 \n\n# add files to the archive\nborg create test1::first \/path\/to\/files\n\n# verify\/check the archive\nborg info test1<\/code><\/pre>\n\n\n\nMy test case gave 50% savings:<\/p>\n\n\n\n
Original size Compressed size Deduplicated size\nAll archives: 50.42 GB 35.15 GB 25.58 GB\n\n Unique chunks Total chunks\nChunk index: 215930 520240\n<\/code><\/pre>\n\n\n\nDon’t forget that you can mount borg archives to browse files. <\/p>\n\n\n\n
borg mount test1::first \/mnt\/borg\nborg unmount \/mnt\/borg<\/code><\/pre>\n\n\n\nTest restore on another host:<\/p>\n\n\n\n
# bundle up the directory\ntar czpvf test1.borg.tgz test1<\/code><\/pre>\n\n\n\nOn another host:<\/p>\n\n\n\n
# retrieve from original host\nwget http:\/\/yourdomain.com\/test1.borg.tgz\n\n# unpack the archive\ntar xzpvf test1.borg.tgz\n\n# check\/verify the archive\n\/usr\/local\/sbin\/borg info test1\nWarning: Attempting to access a previously unknown unencrypted repository!\nDo you want to continue? [yN] y\n\n# create a directory to restore to\nmkdir restore\n\n# mount the archive\nborg mount test1 restore\/\n\n# work with the files in the archive\n# ls restore\n\n# umount the archive\nborg umount restore\n\n# extract all files from the archive\n# first, list the snapshots\nborg list test1\n\n# extract a snapshot\ncd restore\/\nborg extract ..\/test1::first <\/code><\/pre>\n\n\n\nCreating an encrypted backup<\/p>\n\n\n\n
Adding encryption is easy :<\/p>\n\n\n\n
# create an empty, encrypted archive called test1\n# enter the passphrase when prompted\nborg init -encryption=repokey test1 \n\n# export the key\nborg key export test1 test1.key\n\n# create the archive\n# enter passphrase when prompted\nborg create test1::first \/path\/to\/files\n\n<\/code><\/pre>\n\n\n\nHistory:<\/p>\n\n\n\n
