Full FIle Backup

Im trying to do a full file backup of about 1Tb over the internet.
evrything works fine except 2 large files that keep failiing with the following error.

These files are all on a different drive/partition. Is it possible that DattoDB is not working for that drive?

I tried this twice and it took a week each time

This is the errors I get:

You could look at the client side debug log file to see if it is backed up via snapshot?

If a file is backed up without snapshot while the server thinks it is backed up via snapshot and the file changes during backup you’ll see those errors, yes.

I turned on debug logging for this client, It still fails and it seems to me that the snapshot IS indeed working for taht partition

The files that fail are super large .pst (outlook files)

What do you think?
This is the relevant parts of the log file (The start of a new one and the end of failing previous one):

Are those archive*.pst files open in anyone’s outlook application?

If they are open, they will be locked, and you will not get a good snapshot of them. Plus, Outlook will make changes to them.

Im not sure I understand.
Isnt that why I use datto (likle windows shadow copy)?

PST files are a known problematic entity for backups, and have been for years (decades, really).

Check out this thread for just one example of the issues/complaints: Is Outlook compatible with Volume Shadow Copy Service? - Data Backup - Spiceworks

If the file is open in someone’s Outlook app, the timestamp on the PST will keep getting updated, which will make it seem like it is steadily changing.

Newer versions of Outlook (such as 2016 or 2019) should be able to backup a PST via VSS, but I haven’t seen an article from Microsoft to substantiate this as yet.

Can’t you upload/post a complete log, not just the start of one? Also, what client version are you using?

Sure, no problem. Just for testing I excluded those large pst files, but I still have large VHDs that fail the backup.

The debug log has all the hashing and filenames in it, can it be posted on the forum?

Depends on if you want everyone know your filenames and sizes :wink: Alternatives are described here:

Unless I can send it on private message for you to look at.

There is just so many files the backup is huge 1.2 TB of files and the debug log will be pretty large too of course

I finally run the failing backup and collected all the debug backup log. The total is 580MB of stuff. how can I share that?

I sent an email to bugreports@urbackup.org that has the log files. thank you so much for looking into this

Ok, so it uses the snapshot and the simplest transfer method (full file transfer).

Is there anything in dmesg w.r.t. dattobd after such a backup?

im not sure what w. r. t. is … but here is the dmesg output for that client:

Not sure about the relevant events (the USB plug and unplug is normal)

So it crashes? Maybe debug this? (See link above for how to)

WOW Thanks, I will

I wish I didnt have to bother you. Than k you so much, Ill look into it and I’ll post the finfings

…I see I have to compile the client … ill see how far I get with it. I used to run gentoo in the past, so I used to have to compile everything, so we’ll see if that will help.

Thank you for your help

I think the version with debug symbols should also work (page should be updated, I guess): https://hndl.urbackup.org/Client/2.4.11/UrBackup%20Client%20Linux%202.4.11-dbg.sh

Awsome
