Written on the Linux shell language. Collects data from clients via share protocol SMB(CIFS) – does not require installation additional software on Windows clients. Data is stored efficiently and with fast access, as well as their temporary versions thanks to the BTRFS and ZFS file systems. The network channel is rationally used due to Rsync – only new / changed objects are copied.
The inspiration for each client’s per-file configuration is the Bareos backup system. Backup steps are represented by alternating files – steps. The length of Cyrillic filenames is limited to 124 characters, but with BTRFS this can be bypassed using the Etersoft Btrfs VLFN article.
- Server system requirements: Linux, BTRFS или/и ZFS, Rsync.
- Compact data storage;
- Fast access snapshots;
- Snapshots do not depend on each other;
- Logging changed objects.
- No shadow copy support;
- The error log gets reduant information;
