PROBLEM: When ffs is run, to sync machine A and machine C, using portable usb disk B as a middle man, the .sync.ffs_db file on B is useless as it is machine specific to the last machine that used the external hdd B.

This means ffs cannot move/delete files properly amongst other errors noted. The ...

Pending an update with feature as requested above, I've created a manual solution.

1. AB - after sync is complete rename B .sync.ffs_db to another name such as machineA.sync.ffs_db

2. BC - after sync is complete rename B .sync.ffs_db to another name such as machineC.sync.ffs_db

3. AB - When ...

Ignore above post.

I've realised that ffs is NOT able to sync between multiple machines properly like you said as ff_db is unique to each machine.

Could I please propose the following solution:

1. When ffs is run by machine A, create ff_db on A and another on B. However, append machine A network ...

Hi,

Just slightly confused by your answers which suggest that ABC can't be sync properly as ff_db is particular to each machine.

After setting the right path for B (my silly error - so ignore my problem post), I've done a few tests and found the following all work:

1. AB - sync
2. BC - manually ...

Hi,

Just one comment on issue (6).

a. I did AB sync. Files added to A and B from each other.
b. Then I did BC sync. Files added to b and C from each other.

c. I went back to A (which had been off throughout so no new files added). I did AB sync expecting new files from B (as received from C) to ...

Thanks so much for the clarification.

If ffs won't be able to detect file deletions, then it would be too cumbersome to do manually each time so I might have to look for another solution.

This is a real pity.

Do you think there might be a way in future to keep a database on portable B, which isn ...

Thanks for the answers as very useful. 1-5 are clear now.

Just a few more queries as below:

6. B is the portable USB hdd to sync between site A laptop and site B laptop. So if I sync AB, then BC, then AB again (no changes to A) - then all three should be sync?

7. What I meant was, if I mount ...

Hi,

Newbie query here.

I have 4 storage locations.

A. laptop A - EXT4 - Local
B. USD HDD B - BTRFS ZSTD:10 - Offline
C. laptop C - NTFS - Offsite
D. online cloud D (eg. PCloud) - Online

1. When I sync AB it creates .sync.ff_db at root of sync. Is .sync.ff_db duplicated between AB or is there a ...
