code 29 error on incremental backup

[Guest]

And attempting to restore the sparse file results in an error, while restoring another file in the backup does work.

Please send me or post the CBU.exe.log and CBU.exe.logold.log in %TEMP%\ComodoLogsFolder.

Thanks

When I restore from incremental back up with the new cbu.exe results in an error.

Here are those files...

Thanks.
Here is the fixed GUI.exe
GUI.exe (32 bit OS)
GUI.exe (64 bit OS)

Previous GUI.exe was fixed only for full cbu backups, now it is fixed for incrementals also.

I notice that during a restore (it works now, thanks) that the process size of CBU.exe grows to approximately the size of the sparse file that it is restoring...

Is that expected? If so, I think there could be some problems with restoring files like DVD images which are 4.5Gb on machines with less than that amount of physical memory, regardless of how many other apps are running or not.

No, probably it's just a coincidence.
The size of used memory depends on the number of files and folders and their total size.
For 100GB of data with 100.000 files it shouldn't consume more than ~200MB of memory.

That was the only file I restored - nothing else - and the file size (on disk use) was very close to the same as the CBU.exe process size. I don't think that's a coincidence.

Maybe it's because I restored to a different location, rather than the original folder? Or that the sparse file is handled differently on restore?

The memory consumption is pretty much the same whether you restore a single file or all the files.
Sparse files are not handled differently than normal files from memory consumption perspective.

Just did a test:

- restore one bank statement - memory use of 77Mb

- restore 630Mb sparse file - memory goes to about 730Mb, growing while the GUI says "processing item" for that file, then dropping back to about 690Mb when the operation is complete.

- restore a 700Mb non-sparse file - memory goes to 140Mb then back down to 114Mb.

Something appears wrong with the sparse file handling and memory use.

In fact, when restoring from an incremental, the memory leaked even more and eventually hit about 1.8Gb before the restore of the sparse file failed because the system ran out of memory.

Yes, you are right.
We found the cause and fixed it.
Here are the new executables:
GUI.exe (32 bit OS)
GUI.exe (64bit OS)

Thanks

Looks fixed, at least the huge leak is gone.

There's still a 10Mb or so "leak" for each version of the file that's processed in subsequent incremental backup files - the process size is fairly constant during each "processing" phase, but jumps up by 10Mb each time that another .cbu backup file is processed.

With the last GUI.exe when the incremental back up is complete appears this screen and the program closes !!
What's the problem ??!!

HELP ?

[Emanuel Sescu]

Hi

I need a dump file to determine the cause of the issue.
Please follow these steps here to create it.
Let me know if you need further help in creating the dump file.

Thanks
