Right now, as far as I can see, it's only possible to have one single backup at one time. The file structure is like so

OAndBackupX/app/app.zip
OAndBackupX/app/app.log

What if we just created numbered directories that contain the backups, something like this

OAndBackupX/app/1/app.zip
OAndBackupX/app/1/app.log
OAndBackupX/app/2/app.zip
OAndBackupX/app/2/app.log
...
OAndBackupX/app/99/app.zip
OAndBackupX/app/99/app.log

To make it easier to see which backup is which we could show the date the backup was created in the UI (like it already does but show them as a list instead) or even add an optional "Description" field to the log file.

To keep the app backwards compatible, we could check if the numbered directories exist, and if they don't, move the content of app/ to app/1/

What do you think?

P.S. Why are the files .log if they just contain json data? Why not .json?

Please provide a non root backup method. It would be able to back up the apks and the data that is on the SD card even if it can't access the data partition.

While having selected APK+data backup and starting to back up apps, users may notice longer backups on apps with bigger data (games, browsers). For those, the app could add a button to skip app data and just back up the APK if it has taken long enough (10 seconds+).

There are some map files but only 13kb files are backuped. The old oandbackupx directory is as 10x large as the new OAndBackupX. I guess there are some other apps which are not backuped completely.

i cant seem to make the app remember "sort" as well as "filter".
even after toggling in settings, it doesnt work.
if there something, i m doing wrong?1

App crashes on start up on my pixel 3a running the April update. It is granted permission and allowed root. I tried the arm64 and universal versions of the newest version of the app. I'll grab a log in a bit and post it.

Some links (e.g. changelog) point to the origin repo. This is a little confusing. Thanks!

When an app is restored from a backup, it is installed to the Work Profile even if the app wasn't originally installed to the Work Profile.

I am using an app called Shelter to make use of the Work Profile feature in case you would like to test this behaviour.

For reference, Titanium Backup doesn't do this.

The app is great....
Pls consider to add a option to backup obb as well as external storage file of app
i think this feature will make this one of a kind.

jensstein#280

TB prompts to close the app (which is being restored) on the background.

I manage work profile with shelter. When I restore an app it will be installed on both sides.

Hi!
For some apps I would like to save the external data. For others like OSMand or Antennapod I don't want to save the external data, because it is too large. Maybe you could add something like a blacklist for apps, which external data is not to be saved.

arm64 version

As the title said, it's borken here. Tried to select the folders instead of root of sdcard, same issue. Iirc OG oandbackup is able to backup to sdcard. Here's the log.

Do you plan to bring back the support of OpenPGP encryption with Openkeychain?

as a backup app a possible usecase is to migrate data from an old phone to a new one.

currently android 7 is required but old phones often have lower android versions, so it would be good to be able to install this app on lower android versions.

Hello, I have filed an issue in the F-Droid repository. Here is the link in case you are interested: https://gitlab.com/fdroid/rfp/-/issues/1316

While performing a backup of all apps, if the backup fails, there are lots of errors in the displayed log about "AnySoftKeyboard: rm: /data/data/com.menny.android.anysoftkeyboard/cache/*: No such file or directory".

** Solution could be to add '-f' (force) flag to "rm -r " in src/main/java/com/machiav3lli/backup/handler/ShellCommands.java for all rm commands so that it performs an "rm -rf" instead.

Running the version from f-droid, android 9, custom ROM, magisk root. Regular oandbackup works without errors but when I backup apps with oandbackupx I get these errors on some apps.

A gzip compressed tar file would be a much more natural format for backups, as tar files store information like file permissions, owner, group, symlinks as core information. Most Linux distributions come with gzip and tar by default, and WinRAR, 7Zip, PeaZip, etc can open .tar.gz files easily for Windows. This would get rid of the need to correct file permissions and ownership after restoring the app's data. The tar format is very simple and there are implementations such as JTar or Apache Commons Compress, both under the Apache License.

An alternative option instead of migrating to .tar.gz, is to keep using zip files, but store the unix information inside the zip file. The upper two bites of the "external file attributes" store the unix permissions, and file type (regular, directory, symlink, device, socket, etc). A 0x7875 header is added in the "extra data" to store the unix ownership. Unfortunately, the zip implementation in Java does not give you access to the internal/external file attributes and always writes 0 for both. The implementation in Apache Commons Compress does let you handle this field though.

if 'Backup device protected data' is enabled, attempting to backup an app will crash oandbackupx.

It might be related to the verifier_verify_adb_installs setting. I cannot execute the needed pm install command via adb until I switch it off.

$ settings get global verifier_verify_adb_installs

Command to switch it off.

$ settings put global verifier_verify_adb_installs 0

Please consider keeping this great feature rather than removing it.

On Essential PH-1 Stock February update, data for rif is fun can't be backed up. The message "backup (circle animation)" shows up but it doesn't get past that.

• rif is fun version 4.116.7
• oandbackupx arm64 version 0.9.4

This is also an issue in oandbackup.

Thanks for reading.

Since some split apks can't be restored by the app..I personally redownload them from the source ,however the option to restore only data isn't there..
This is my first time time in github,so point me if I m wrong somewhere..
Thx

The original oandbackup includes matching package name when searching:

oandbackupx doesn't:

Hope this can be added as it's quite useful

In the readme it says, oandbackupx can be combined with syncthing or nextcloud for remote backups. However how is it actually possible to push those backups to Nextcloud? The backup location is a custom folder picker, so I can't choose Nextcloud via the Storage Access Framework, so there is no way to use Nextcloud? I could only select a data directory of the nextcloud app, however since it doesn't use the framework nextcloud isn't notified of any changes, and my backups won't be uploaded.

Thanks!

Using oandbackupx 0.9.11-arm, it restores the data in Bromite 81.0.4044.127 but then the browser doesn't browse anymore. I can't open any site.

I should mention the data backup was made with oandbackup 0.3.5.

(already reported this issue for oandbackup so apologies for the crosspost, but it also affects
oandbackupx)

I can't get OandBackupX to backup to external SD.
When selecting a folder on the external SD, I get an error (something like "Can't create...")

Is there any chance to get backup to external SD (probably through Storage Access Framework) ?

A workaround could be the ability to configure any folder, including ones outside user storage area (I've been using Oandbackup configured to backup to "/mnt/media_rw/..."). Can such a setting be configured ? (can be through adb commands if there's no other possibility)

doesnt do anything when i click it.

oab-utils will follow symlinks which can break some applications on restore. For example: if the application data has a lib symlink, it will follow it which leads to broken ownership and permissions for /data/app/(package)-1/lib/(arch), which may cause the application to malfunction or be considered not installed.

Hi, the new update(0.9.12) improved the force close issue by much, though there are still some, but broke the backup function. The logs for the fc issue are those (basically two errors xD) https://del.dog/crilegutul
The error for the backup issue is this
2020/05/14 - 04:48:25: /system/bin/sh: [1]: rsync: inaccessible or not found.
Also, I may refer to some ui stuff, the splash screen doesn't quite show up, it flashes quickly and then fades out. Pull down to refresh also doesn't work very good, icon gets dragged back immediately after pulled down in a choppy motion and I'm not sure if refreshing is actually done. Other than these great work, keep it up😃

Some applications store some data in this path, OAndBackupX should also save that data too
There was a pull request for the upstream code that the original author didn't look at, maybe it could be included in this fork?
jensstein#267

I backuped all my app on Android 9 and restored them on Android 10. Some apps doesn't work or can't restore settings:

• Muzei: Settings are not restored
• Termux: Doesn't work after restored. It seem that some bin are missing.
• Librera Reader: Setting are not restored Config files are stored in external storage.
• NClientV2: Can't recognize downloaded files Download path is changed. Android version related?
• RemoteFiles: Stuck

OAndBackupX crashes after every restoring. It works but just crash which is strange.

OS: Android 10

OandbackupX version: 0.9.7-universal

Description: Application crashes when trying to back up app+data (package: Protonmail)

Steps to reproduce: Try to back an app up on fresh install

Log: https://del.dog/nexelemebe

It would be great if there was an option to exclude caches from the backups, since the cache usually does not include necessary / non-reproducible data, but instead tends to make the backups unnecessarily larger.
This could be implemented by just ignoring the folders called cache, since this seems fairly standardized.

The next level would be to also include the ability for a per-app black- or whitelist, however this per-app setting is probably not necessary for most users.

Mark and Tags are very useful for batch action,

The mentioned errors occur on symlinks and special files like named pipes:

Hi,

would it be possible to run OAndBackupX without root as a system app (priv-app)? If it would have enough permissions given that sepolicy has rules for?

When backup a large app, progress bar is very useful. Could you please add one? Thanks!

Hi,

I am not able to backup apps or data. It shows error=13 as shown in the screenshot:

Best regards

Hi, firstly thank you for resurrecting and improving OAndBackup!

The biggest problem at the moment I am having with the app is that Android kills the backup process, perhaps this can be avoided by making a persistent notification when performing a backup.

And it would also be a good idea to request a battery optimization exception.

My device info:

• Xiaomi Mi 9T
• Android 10 (Pixel Experience+)
• Magisk v20.4 (Stable)
• OAndBackupX v0.9.8-arm64

Different than the other "shelter" issue since in that apps got installed in both work and primary profile,however in this case the apps get restored in only work profile

Fix- 1) Restore ur app
2)after installing check whether your work profile has that app or not.
3) if yes, navigate to the backup folder and install that app from the base.apk
4)uninstall app from work profile
Note- after installing base.apk in primary profile, u will automatically get ur data since u restored it earlier (given in step 1 u selected "apk+data")

It would be good to move functional buttons in the app from bottom because those are blocked by root popups (and there's really many of them) which renders app unusable for some time.

I need to backup restore feom KitKat to Oero.
So I would need to use oandbackup to backup and yours to restore.
Would that work?
Or maybe you can lower the minsdk?

If 'Clear app's cache' is enabled, if the cache directory doesn't exist (such as being cleared in a previous backup), oandbackupx will close and relaunch.
This is in the log:
rm: /data/data/arun.com.chromer/cache/*: No such file or directory [Lynket]

Hello,

could you think to add OABX to F-Droid ?

Thanks :)
