Previosly u64 numbers was truncated to u32 numbers during writing to the mdatadata xml file, and further incremental backup cannot reuse them, since the file in base backup is smaller. P.S. There can be other places, I thought about enabling -Wshorten-64-to-32, but there are lots of warnings right now. Signed-off-by: Azat Khuzhin <a.khuzhin@semrush.com>
