A HTTPS service to hold your backup files.

Key features:

• works over HTTPS, uses certificates from user supplied PEM files.
• multi user support, holds files per user.
• uses HTTP digest authentication for checking user's passwords.
• allows continue of upload at any time, but only until the file becomes completely uploaded.
• writes to actual files through the special journal(transaction) files.
• runs as a Windows service or command line.
• runs on Linux.
• server side can listen on two interfaces at a time.
• server gracefully waits for root storage to be attached by administrator after a service start.
• server has web UI with a list of your files at https://ip:port/upload/:username/
• this repository includes packages for server and client.
• the client side (uploader) marks all successfully uploaded files with unset of 'A' attribute on Windows, or with 'user.uploaded' xattr attribute on Linux. This attribute is used in other tools from "A DBA backup files tool set.": BackupsControl, DeleteArchivedBackups
• client uploader stores user password in DPAPI if on Windows.
• client side may also upload to a ftp server.
• rotation of backup files accomplished by standalone command DeleteArchivedBackups that you run on server side from a scheduler.
• has a readonly web interface:
  ** https://....../upload/:username
  ** https://....../log
  ** https://....../debug/pprof

To download a service:

go get -v github.com/zavla/upload

To compile binaries run at upload root directory:

or build.ps1
or build.sh

This will run 'go build' for every /cmd/... with commit id compiled in.

Usage:

Users may upload files using specialized uploader (which supports continue of upload) :

uploader.exe -username zahar -file .\testdata\testbackups\sendfile.rar  -passwordfile .\logins.json -cacert ./mkcertCA.pem -service https://127.0.0.1:64000/upload

or uploading the whole directory (no recursion) :

uploader.exe --username zahar --dir .\testdata\testbackups -passwordfile .\logins.json -cacert ./mkcertCA.pem -service https://127.0.0.1:64000/upload

To launch a server of the service on command line:

You will need two files in PEM format with service's certificate e.x. 127.0.0.1.pem, 127.0.0.1-key.pem. You need to generate certificate pair by yourself.
I prefer https://github.com/FiloSottile/mkcert for this.

uploadserver.exe  -log .\testdata\service.log -root .\testdata\storageroot\ -config ./  -listenOn 127.0.0.1:64000

To create a Windows service on Windows run:

INSTALL_uploadserver_as_a_service.ps1

The Service command line parameters:

Usage: 
uploadserver -root dir [-log file] -config dir -listenOn ip:port [-listenOn2 ip:port] [-debug] [-asService]
uploadserver -adduser name -config dir

  -adduser string
    	will add a login and save a password to logins.json file in -config dir.
  -asService
    	use it in ImagePath of a Windows service when you launch uploadserver as a service.
  -config directory
    	directory with logins.json file (required).
  -debug
    	debug, make available /debug/pprof/* URLs in service for profile
  -listenOn address:port
    	listen on specified address:port. (default "127.0.0.1:64000")
  -listenOn2 address:port
    	listen on specified address:port.
  -log file
    	log file name.
  -root path
    	storage root path for files.
  -version version
    	print version

API usage Example

func ExampleSendAFile() {
	// a jar to hold our cookies
	jar, _ := cookiejar.New(&cookiejar.Options{PublicSuffixList: publicsuffix.List})

	// specify where to connect
	config := uploadclient.ConnectConfig{
		ToURL:    "https://127.0.0.1:64000/upload/testuser",
		Password: "testuser",
		//PasswordHash: string, // you better to use a hash of a password
		Username:           "testuser",
		InsecureSkipVerify: true, // skips certificates chain test, don't use 'true' in production, of course use a CAPool!
		//CApool: *x509.CertPool, // a root CA public certificate that signed a service's certificate

	}

	// use context to have a cancel of a long running upload process
	ctx, callmetofreeresources := context.WithDeadline(
		context.Background(),
		time.Now().Add(time.Second*10),
	)
	defer callmetofreeresources()

	const filename = "./testdata/testfile.txt"

	// compute sha1
	sha1file := sha1get(filename)

	err := uploadclient.SendAFile(ctx, &config, filename, jar, sha1file)
	if err != nil {
		println(err.Error())
		return
	}
	println("Normal OK:")
	// Output:
	// Normal OK:
}
