Hi, my wife has just bought a new phone.
On her old phone we have used DAVx5 (and previously DavDroid) to sync her calendars and contacts with our Synology network drive. This has always worked well and I also use it for my Android phone.
I installed Davx5 on her new phone, added her calendar accounts and then added her address book account. It found her address book account easily enough by using the same URL as used on her old phone.
I then synced her contacts but the sync only lasted for a second which I thought wasn’t long enough to have downloaded her whole address book and, sure enough, her new phone had no contacts on it. I tried again and the same happened. I then left if for a few hours because I was busy with other things.
However, later that day, my wife was using her laptop and discovered that all of her contacts had been deleted. I cannot understand what has happened but it appears that, instead of downloading my wife’s contacts from the network drive to her phone, it has uploaded her ‘empty’ address book from her new phone to the network drive and deleted all of her contacts.
This is very bad. I assumed that I would be able to restore the address book database from my backup Synology drive because I do a daily backup of all files and application data (calendars, address book etc.). However, Synology have just told me that this process does not actually back up the contact data itself and that there is no way to do this without manually exporting the address book and saving it somewhere.
I know the shortcomings with Synology’s backup process is not your fault but the result is that my wife has now lost ALL of her contacts and it appears to have been DAVx5 that has caused the data loss. Clearly, I may have done something but all I did was set up the account and tap the ‘sync’ button as I’ve done many times on our old phones.
Can you explain how this has happened?
