Incremental "backuper" of local files to some storage.

Implemented types of storage (the list could be easily expanded):

• local filesystem
• Amazon Glacier

The application does NOT synchronize a local folder with a remote one (and vice versa). It designed to work like this:

• finds files/folders which have not been backed up (or have been changed) in guarded directories
• splits obtained list of files on chunks (by default, chunk size - 1GB)
• for each chunk
  • composes archive with files form chunk
  • writes list of files into meta info file
  • uploads the archive to storage
  • saves a copy of meta info files locally and uploads them to storage

Some features:

• supports many backup plans on one computer
• supports data encryption before uploading to storage
• supports files restoration in accordance with chosen recovery point
• by uploading only small number of large archives, supports a high speed of initial uploading
• could be terminated any time (this leads to reprocessing only one chunk/archive)
• command-line interface for managing backup plans
• web interface for analizing backed up files/folders, and used capacity

> backuper.exe
usage: D:\...\backuper.exe --create-plan
       D:\...\backuper.exe --plan my_plan_name --<command>
possible commands:
    --edit
    --view
    --status
    --backup
    --restore
    --sync
    --web-ui

After creation of backup plan (it is interactive), we can view created plan details:

> backuper.exe --plan backup_test --view
Plan name: backup_test
Limit size of one archive (MB): 100
Encrypt data: Yes
Encryption/Decryption passphrase: 12345
Pathes to backup:
    C:\Dir1
    C:\Dir2

Storage type: glacier
AWS Region: eu-central-1
Vault Name: backup-test
Access Key ID: qwerty12345
Secret Access Key: 12345qwerty

Common task to be run by daily/weekly schedule:

> backuper.exe --plan backup_test --backup

Command to use web interface:

> backuper.exe --plan backup_test --web-ui

Use --sync command to restore metafiles from remote storage (usually they are stored locally). To restore data files use interactive command --restore.
