Restore UT OTA-15 data backup (Meizu MX4) to UBPorts OTA-2 (Nexus 5)

  • Re: What do I need to back up my Meizu MX4 before I start installing onto it?

    I have always used the buds script for backing up my Meizu MX4 ( I have now installed UBports OTA-2 on a Nexus 5. And I would ideally like to restore my Meizu data on the Nexus 5, using the buds backup.

    I suppose the main folders (Documents, Pictures, Music, Videos, Downloads) can be plainly copied as such. But I was also hoping to restore some of the hidden config folders. I would e.g. like to have my notes, phone history, messaging history, contacts, browser favorites, Tasks, UNav favorites and calendar entries back. Any suggestions, references in this regard? If not, I will just try and report my findings in this post for future reference.


  • I did a rsync of my /home/phablet of a Bq E5 to my PC and then again rsync from the PC to the /home/phablet of a Nexus 5, and after installing the same apps I had in the Bq E5, the configurations and most of the data of the apps were restored in the Nexus 5.

  • Thanks!

    As I had many apps installed that I now don't plan to install any longer (because not yet in OpenStore or not needed), I don't think a complete rsynch would serve my needs. I also don't see the need to restore the .cache folder. And for some files/folders I see a risk of creating incongruencies by synching them (e.g. .local/share/zeitgeist)

    So, I tried to drill down to the individual files and folders needed.

    I managed to restore those configurations that are linked to individual files:

    • phone and messaging history: .local/share/history-service/history.sqlite

    • browser bookmarks: .local/share/webbrowser-app/bookmarks.sqlite

    • Dekko address book: .local/share/dekko.dekkoproject/addressbook.sqlite

    • contacts: .local/share/evolution/addressbook/system/contacts.db

    I however so far failed to restore my notes (in .local/share/com.ubuntu.reminders/@local), tasks (in .local/share/evolution/tasks - EDIT 29092017: incorrect assumption, probably in .local/share/com.canonical.scopes.tasks/Databases) and calendars (multiple ones, in .local/share/evolution/calendar).

    @wgarcia, did your approach restore them correctly?

    I managed to use terminal app on UT
    syncevolution --print-databases
    to get DB name which is affect by the "display language". For instance in english, it gives

    Evolution Address Book = Evolution Contacts = evolution-contacts:
    Personal (system-address-book) <default>

    Evolution Calendar = evolution-calendar:
    Birthdays & Anniversaries (birthdays)
    Personal (system-calendar) <default>

    Evolution Task List = Evolution Tasks = evolution-tasks:
    Personal (system-task-list) <default>

    Evolution Memos = evolution-memos:
    Personal (system-memo-list) <default>

    1- backup:
    syncevolution --export ./utcalendar.ics backend=evolution-calendar database=Personal
    syncevolution --export ./utcontacts.vcf backend=evolution-contacts database=Personal

    syncevolution --import ./utcalendar.ics backend=evolution-calendar database=Personal
    syncevolution --import ./utcontacts.vcf backend=evolution-contacts database=Personal

    I didn't try with task list and memos, but it might work the same...

    I'm having bad luck though, as just yesterday my Meizu died (battery drained, requiring me to bring it to the repair shop to have it recharged externally, something I did several times in the past, but which -given my new phone- I'm hesitating to do again now).

    So, at least for now I cannot carry out the backup step. But ... the import might still work, given that I have the ics files and provided that I find another way to retrieve the DB names. I'll try and let you know.

  • Update: I managed to restore all my calendars.

    For each calendar .local/share/evolution/calendar/X/calendar.ics, the corresponding X.source file also had to be restored in .config/evolution/sources. Hence, no explicit syncevolution import operation was needed, only file copying (EDIT, to be complete: I first copied the source files, after which automatically empty calendars were created for each new source, and then I overwrote the empty calendar.ics files with the backed up versions).

    The main DB (with display name 'Personal' in my and the default case) could be restored just by restoring .local/share/evolution/calendar/system/calendar.ics.

  • Update: I also managed to restore my Tasks. I wrongly assumed they were inside .local/share/evolution/tasks. Instead, they were inside .local/share/com.canonical.scopes.tasks/Databases.

    I realized that the Tasks program was not inside the Openstore yet, so I installed it again from the Ubuntu Store. Afterwards I created the .local/share/com.canonical.scopes.tasks/Databases folder (wasn't created automatically after installation, maybe because I had not launched the app yet), and copied the backup files (.ini file + .sqlite file) in there.

    Hi dad_and_alive,

    I also own a MX4, currently with OTA15. Did you try UBports OTA2 on yours?


  • @wilfridd No, I didn't.

    I intentionally bought a second hand Nexus 5 as arale was not listed as one of the Ubports core devices. And my idea was to keep the Meizu as a reference device for testing purposes (but, alas, now I cannot even start it up any longer).

  • @dad_and_alive

    Sad... My daily driver MX4 is still OTA15 and performing quite well. I recentlly added UT Openstore to keep some SW up to date as far as possible. I bought a second hand N5 too but for testing purposes.
