🔒 It's secure
knoxite uses AES-encryption to safely store your data.
💪 It's flexible
You can always extend your storage size or move your stored data to another machine.
🚀 It's efficient
knoxite cleverly de-duplicates your data before storing it and supports multiple compression algorithms.
🔗 It's connected
You can use multiple storage backends, even parallely: local disks, Dropbox, Amazon S3 & others.
❤️ It's OpenSource
knoxite is free software. Contribute and spread the word!
Installation
Make sure you have a working Go environment. Follow the Go install instructions.
To install knoxite, simply run:
git clone https://github.com/knoxite/knoxite.git
cd knoxite
go build ./cmd/knoxite/
Or use your favourite package manager:
# Arch Linux (btw)
yay -S knoxite-git
Run knoxite --help to see a full list of options.
Getting started
Initialize a repository
First of all we need to initialize an empty directory (in this case /tmp/knoxite) as a repository:
$ knoxite -r /tmp/knoxite repo init
Enter password:
Created new repository at /tmp/knoxite
knoxite encrypts all the data in the repository with the supplied password. Be warned: if you lose this password, you won't be able to access any of your data.
Initialize a volume
Each repository can contain several volumes, which store our data organized in snapshots. So let's create one:
$ knoxite -r /tmp/knoxite volume init "Backups" -d "My system backups"
Volume 66e03034 (Name: Backups, Description: My system backups) created
List all volumes
Now you can get a list of all volumes stored in this repository:
$ knoxite -r /tmp/knoxite volume list
ID Name Description
----------------------------------------------------------------------------------------------
66e03034 Backups My system backups
Storing data in a volume
Run the following command to create a new snapshot and store your home directory in the newly created volume:
$ knoxite -r /tmp/knoxite store [volume ID] $HOME -d "Backup of all my data"
document.txt 5.69 MiB / 5.69 MiB [#########################################] 100.00%
other.txt 4.17 MiB / 4.17 MiB [#########################################] 100.00%
...
Snapshot cebc1213 created: 9 files, 8 dirs, 0 symlinks, 0 errors, 1.23 GiB Original Size, 1.23 GiB Storage Size
When errors occur while storing individual data-chunks knoxite still tries to
complete the store operation for the remaining chunks. You can toggle this
behaviour to immediately exit on the first erroroneus data-chunk by setting the
--pedantic command line flag.
List all snapshots
Now you can get an overview of all snapshots stored in this volume:
$ knoxite -r /tmp/knoxite snapshot list [volume ID]
ID Date Original Size Storage Size Description
----------------------------------------------------------------------------------------------
cebc1213 2016-07-29 02:27:15 1.23 GiB 1.23 GiB Backup of all my data
----------------------------------------------------------------------------------------------
1.23 GiB 1.23 GiB
Show the content of a snapshot
Running the following command lists the entire content of a snapshot:
$ knoxite -r /tmp/knoxite ls [snapshot ID]
Perms User Group Size ModTime Name
----------------------------------------------------------------------------------------------
-rw-r--r-- user group 5.69 MiB 2016-07-29 02:06:04 document.txt
-rw-r--r-- user group 4.17 MiB 2016-07-29 02:05:22 other.txt
...
Show the content of a snapshotted file
With the following command you can also print out the files content to stdout:
$ knoxite -r /tmp/knoxite cat [snapshot ID] document.txt
This is the sample text stored in document.txt
Restoring a snapshot
To restore the latest snapshot to /tmp/myhome, run:
$ knoxite -r /tmp/knoxite restore [snapshot ID] /tmp/myhome
document.txt 5.69 MiB / 5.69 MiB [#########################################] 100.00%
other.txt 4.17 MiB / 4.17 MiB [#########################################] 100.00%
...
Restore done: 9 files, 8 dirs, 0 symlinks, 0 errors, 1.23 GiB Original Size, 1.23 GiB Storage Size
Cloning a snapshot
It's easy to clone an existing snapshot, adding files to or updating existing files in it:
$ knoxite -r /tmp/knoxite clone [snapshot ID] $HOME
document.txt 5.89 MiB / 5.89 MiB [#########################################] 100.00%
other.txt 5.10 MiB / 5.10 MiB [#########################################] 100.00%
...
Snapshot aefc4591 created: 9 files, 8 dirs, 0 symlinks, 0 errors, 1.34 GiB Original Size, 1.34 GiB Storage Size
Mounting a snapshot
You can even mount a snapshot (currently read-only, read-write is work-in-progress):
$ knoxite -r /tmp/knoxite mount [snapshot ID] /mnt
Backup. No more excuses.
Configuration System
Knoxite comes bundled with a configuration system. You can declare shorthands
for your repositories and provide default values for settings like encryption,
compression or excludes. For more information refer to the documentation on our
website or take a look into
the knoxite config command.
Optional environment variables
Optionally you can set the KNOXITE_REPOSITORY and KNOXITE_PASSWORD environment
variables to provide default settings for when no options have been passed to knoxite.
