Restore is losing some files
#1
I'm using CompanionPro to backup my database from one tablet, and restoring it to another. The restored verison is missing some songs. If I restore again, it's still missing songs, but different ones than the first time. Any help much appreciated!

Mike, I'm pretty certain I have seen this as well. At the time, I was looking at another problem (since solved) but I do recall thinking "I'm sure this file existed" and wondering what had happened to it?

I'll look into it. I'll have to find a backup file I know contains every file but fails to restore every file. Hopefully I can either create one that exhibits that problem or find an existing one that acts like you described.

Same happened to me yesterday, it's the same issue I mentioned when the Pro version was first launched, shows a failed message in the Companion. Majority of files are there, I haven't checked to see how many are missing, it was just the one sheet before. Am looking forward to a sync facility to update libraries across tablets, just transferring the newer sheets.

In case it helps: I don't get an error message when doing either the backup or restore--just a message that it completed successfully (or something like that). On the tablet with the restore, the song list is fine, set lists are fine, but when I try to open the song, I get the error message that the file is missing. I can get exact wording for you if it will help. Also, in case it's relevant, I have more than 2000 songs MS.
Thanks!

I have seen exactly the same as FiddlerJeanne - reports the restore has been successful and everything looks to be OK, until you try to open a file, only then is it reported as missing.

Also, like FiddlerJeanne, I have in excess of 2,000 charts. This makes it very difficult to determine if they are all present, as just about the only way* to do so is to open each one - life's too short to do that - but it does make me wonder if the number of files being stored has any relevance to the problem?

Maybe I should have reported it before, but nobody else had mentioned it and I made the assumption that it was something that I had done - I've changed my mind about this now Wink .

* Using a file manager you can check if each individual directory contains any files, but that's just as tedious a route as opening them.

I have seen databases where many (every?) files had more than one entry. Maybe this is related?
I haven't checked it out further but here are some of the notes I made:
Code:
sqlite> select * from Songs where Title like '%Rescue%';

332|004 Past The Point Of Rescue (Cho)|0|||0|0|0|0|1.0||0|7|1431531833545|1431531833545|
379|004 Past The Point Of Rescue (Cho)|0|||0|0|0|0|1.0||0|7|1431543079625|1431543079625|
sqlite> select * from Files where Path like '%Rescue%';
351|332|/storage/sdcard1/Partituren/HowsaGoin/004_Past_The_Point_Of_Rescue_(Cho).cho|1-2|1354|1431528586000|1|3|
401|379|/storage/sdcard1/Partituren/HowsaGoin/004_Past_The_Point_Of_Rescue_(Cho).cho|1-2|1351|1431542293000|1|3|

Song #332 has size 1354 and timestamp 1431528586000 (Wed May 13 16:49:46 2015)
Song #379 has size 1351 and timestamp 1431542293000 (Wed May 13 20:38:13 2015)

Apparenty, the song of 16:49:46 (1354 bytes) was stored into MSPro,
and later the newer version of 20:38:13 (1351) was added.

So far, so good.

In the backup file (MobileSheetsProBackup.msb) I find the following
data:

For song #332: 1351 bytes
For song #379: 0 bytes

0 bytes indicates that the file should already exist on the file system and it should be skipped. This is how I dealt with duplicate files entries.

I have spent a lot of time investigating this issue. I've worked with a large number of different backups, some as large as 1.6GB. I've made some minor fixes that I didn't think would entirely fix the problem, but since then, I have been completely unable to reproduce a case where I backup or restore a file, and files are missing afterward. I'm going to ask for people to test this again after the next update to see if they are experiencing any more issues. I'm hoping that maybe the problem is fixed.

Thanks Mike - we'll do our best to break it Smile .

My backup is ~ 1.8 GB, including some audio stuff so, if it's a size thing, I would think that would be enough to upset it.

The hardest part of the exercise is determining if any files are missing!

Graeme,
Using a tool (app) like ESFile Explorer, you can long press on a folder, and the choose more/properties which will tell you the number of files and bytes in the folder. Doing this before and after the backup will give you quickly an idea is something is missing or not.
This won't tell you what's missing but at least you will know if something is or not ...

I phrased my original reply badly, I really meant to say that it was hard to determine what was missing when handling such a large collection. Still, I guess it has to be done, as it's possible the problem is related to something specific in the missing file/s, so we need to solate it/them for Mike to look at.

OTOH, maybe it's fixed and we won't have t worry about it Smile .

I do plan on adding some diagnostic options to the settings. One of these would be a tool that goes through the library looking for any songs with missing files and lists them (with an option to delete those songs if desired). Perhaps I'll add this for the next update to make it easier to determine if this bug is still present.

At the risk of stating the bleeding obvious, that would be a huge help.

One slight concern is, if we determine that a file is missing (after doing a restore) we wouldn't have the file for you to examine as to why it might have gone AWOL in the first place - that's a nice Catch 22 situation.

People with 2 tablets will probably test on their backup device, using a backup file from the main device, so the file could be retreived from there in order to send to Mike ..
Apart from that, I also store every score that is present in MSPro on a pc disk . . .
