Backups Failing

[render99]

Backups fail when initiated both on device and by ADB

COT 2.99.10, Hammerhead, Lollipop (LRX210 - OTA from 4.4.4 KTU84P), Franco Kernel r68,

I installed the recovery without issue however whenever I backup using "Backup Now" on the device it appears to backup Boot and System without issue however it appears to fail whilst backing up Data and just returns to the backup menu. Sometimes this leaves a partial file (approx 630mb) in /sdcard/cot/backup and sometimes nothing. I have 5gb space available for the on device backup and the size of all data (boot+sys+data) to be backed up is just under 4.5gb.

If I try to backup via ADB it also fails on data but progresses further and I generally end up with a 2.5gb .ab file.

Do you think this is a device / data issue or something awry in the recovery? I'll gladly provide further info if requested.

Can you grab a log from /tmp/bu.log when this happens?

Hi,

Entire log is as follows:

[187] bu: invoked with 7 args
[187] part_add: i=0, name=boot, path=/boot
[187] part_add: i=1, name=system, path=/system
[187] part_add: i=2, name=data, path=/data
[187] part_add: i=3, name=cache, path=/cache
[187] do_backup_tree: path=/data/misc/wifi/sockets, ignoring special file
[187] do_backup_tree: path=/data/misc/wifi/sockets, ignoring special file

@render99 from the log you send.
i only know, you backup partition /data
but, what happen, can you show the hold log of it .

I expect that is the whole log @sndnvaps
This is an issue that was first noticed on the HLTE and I've since seen it on my Mako.
It is something related to upstream as best as we can tell but as of yet have been unable to ascertain the actual cause.

In this case,
i would add some debug func to the backup func.
print more info when backup the data part.
grap more info

Yes, that is the whole log. Please let me know if I can be of any further assistance.
