1. Napravi ili učitaj šablon

Šablon čuva izabrane izvore, aktivna odredišta, režim rada, FILESYNC proveru i raspored. Koristi različite šablone za različite grupe podataka.

2. Dodaj izvore

Dodaj foldere ili pojedinačne fajlove. Čekiranje u listi određuje šta ulazi u posao. Kod velikih projekata računaj da broj sitnih fajlova može biti važniji za brzinu od ukupne veličine u GB.

3. Dodaj i testiraj odredište

Izaberi lokalni folder, mapirani disk ili UNC putanju. Koristi TESTIRAJ ODREDIŠTA pre prvog važnog posla. FREEWARE omogućava jedno aktivno odredište po šablonu; registrovana verzija više njih.

4. Izaberi REŽIM BACKUPA

• FULL — kompletna nova ZIP arhiva.
• INCREMENTAL — samo promene u odnosu na prethodno stanje; restore koristi potreban lanac.
• SMART SNAPSHOT — kompletno trenutno stanje uz ponovno korišćenje nepromenjenih podataka iz prethodnog ZIP-a kada je moguće.
• FILESYNC UPDATE — prenosi nove i promenjene fajlove, ali ne briše dodatne fajlove sa odredišta.
• FILESYNC MIRROR — kontrolisani folder usklađuje sa Source-om; obrisane/zamenjene stavke idu u Sync Trash.

5. FILESYNC PROVERA: STANDARD ili SHA-256

STANDARD je preporučen za svakodnevni rad i koristi ubrzani OS copy put za nove fajlove, bez dodatnog ponovnog SHA-256 čitanja. SHA-256 dodaje kriptografsku proveru kopiranog sadržaja i namenjen je situacijama gde je maksimalna verifikacija važnija od brzine.

6. Šta se dešava pri prvom FILESYNC-u?

Prvi FILESYNC mora da napravi kontrolisani destination folder i početno sync stanje. Ako se prvi posao prekine, sledeće pokretanje može da očita postojeći destination folder i prepozna već uspešno kopirane fajlove umesto da sve ponavlja.

7. FAST NTFS / USN Journal

Za lokalne NTFS izvore FAST NTFS Helper se podešava jednokratno uz UAC. Posle uspešnog baseline-a program pamti USN checkpoint. Ako je checkpoint i dalje važeći, sledeći posao čita samo NTFS promene i preskače kompletan source scan. Ako checkpoint više nije dostupan ili USN nije bezbedan, TWO BACKUP prelazi na normalno skeniranje samo izabranih izvora i pravi novi checkpoint.

8. Sync Trash u MIRROR režimu

FILESYNC MIRROR ne mora odmah nepovratno da obriše destination fajl koji je nestao ili zamenjen u Source-u. Takve stavke se premeštaju u Sync Trash, što daje dodatni prostor za oporavak od greške korisnika.

9. Koji disk koristiti?

• NVMe / SSD + NTFS — preporučeno kada imaš desetine ili stotine hiljada sitnih fajlova.
• HDD — dobar za kapacitet i velike arhive, ali može biti spor kod velikog broja sitnih fajlova.
• USB flash — brzina malih random upisa veoma varira; nije idealan za veliki FILESYNC workload.
• exFAT — odličan za kompatibilnost između sistema, ali može biti sporiji od NTFS-a pri masovnom kreiranju sitnih fajlova/foldera.

Primer iz razvoja: isti Android skup je na starijem exFAT uređaju radio oko 0,4 MB/s i 8–10 fajlova/s, dok je eksterni NVMe na NTFS-u dostizao oko 4,3 MB/s i ~51 fajl/s. Brojke nisu garancija — služe da pokažu koliko odredišni disk i filesystem mogu promeniti rezultat.

10. Kako tumačiti brzinu?

Kod velikih fajlova MB/s je dobar pokazatelj. Kod Android projekata, source stabala, build foldera i drugih skupova sa hiljadama sitnih fajlova prati i fajlova/s. SSD može biti mnogo brži čak i kada MB/s izgleda skromno.

11. Raspored i automatski rad

Izaberi dane i jedan ili više termina dnevno. Scheduler radi dok je TWO BACKUP pokrenut. Ako više poslova dospe u isti trenutak, trajni queue ih izvršava jedan po jedan i čuva stanje kroz restart aplikacije.

12. RESTORE BACKUP

Izaberi TWO BACKUP ZIP i folder za vraćanje. FULL i SMART SNAPSHOT se vraćaju direktno. Kada izabereš INCREMENTAL, program automatski pronalazi potreban lanac do baznog FULL/SNAPSHOT backupa. Rollback zaštita smanjuje rizik ako se restore prekine.

1. Create or load a template

A template stores selected sources, enabled destinations, work mode, FILESYNC verification and schedule. Use separate templates for different groups of data.

2. Add sources

Add folders or individual files. Checkboxes decide what is included in the job. With large projects, the number of small files can matter more to performance than total GB.

3. Add and test a destination

Choose a local folder, mapped drive or UNC path. Use TEST DESTINATIONS before an important first job. FREEWARE allows one enabled destination per template; the registered version allows more.

4. Choose BACKUP MODE

• FULL — a complete new ZIP archive.
• INCREMENTAL — changes only; restore uses the required history chain.
• SMART SNAPSHOT — complete current state while reusing unchanged data from the previous ZIP when possible.
• FILESYNC UPDATE — transfers new and changed files without deleting extra destination files.
• FILESYNC MIRROR — aligns the managed folder with Source; removed/replaced items go to Sync Trash.

5. FILESYNC VERIFY: STANDARD or SHA-256

STANDARD is recommended for everyday work and uses the accelerated OS copy path for new files without an additional SHA-256 reread. SHA-256 adds cryptographic verification of copied content and is intended for cases where maximum verification matters more than speed.

6. What happens on the first FILESYNC?

The first FILESYNC creates the managed destination folder and the initial sync state. If the first job is interrupted, a later run can inspect the existing destination and recognize already completed files instead of starting from zero.

7. FAST NTFS / USN Journal

For local NTFS sources, FAST NTFS Helper is configured once with UAC. After a successful baseline the program stores a USN checkpoint. While that checkpoint remains valid, later jobs read only NTFS changes and skip a complete source scan. If the checkpoint is no longer available or the fast path is not safe, TWO BACKUP scans only the selected sources and creates a new checkpoint.

8. Sync Trash in MIRROR mode

FILESYNC MIRROR does not have to permanently delete a destination file immediately when it disappears or is replaced in Source. Such items are moved to Sync Trash, providing an additional recovery opportunity.

9. Which drive should I use?

• NVMe / SSD + NTFS — recommended for tens or hundreds of thousands of small files.
• HDD — good for capacity and large archives, but can be slow with huge numbers of small files.
• USB flash — small random-write performance varies widely; not ideal for heavy FILESYNC workloads.
• exFAT — excellent for cross-platform compatibility but can be slower than NTFS when creating very large numbers of small files/directories.

Development example: the same Android dataset ran at about 0.4 MB/s and 8–10 files/s on an older exFAT device, while an external NVMe formatted as NTFS reached about 4.3 MB/s and ~51 files/s. These numbers are not a guarantee; they illustrate how much the destination device and filesystem can affect results.

10. How should I read the speed indicators?

For large files, MB/s is a useful measure. For Android projects, source trees, build folders and other datasets containing thousands of tiny files, also watch files/s. An SSD can be dramatically faster even when the MB/s number looks modest.

11. Scheduling and automatic operation

Choose weekdays and one or more times per day. The scheduler runs while TWO BACKUP is running. If several jobs are due together, the persistent queue runs them one-by-one and keeps its state across application restarts.

12. RESTORE BACKUP

Select a TWO BACKUP ZIP and a restore folder. FULL and SMART SNAPSHOT restore directly. When you select an INCREMENTAL archive, the program automatically locates the required chain back to the base FULL/SNAPSHOT. Rollback protection reduces risk if restore is interrupted.
