GBAK: Strangelly high value for reads and writes stats

[Lucas Schatz]

Hello, so I'm doing a gbak of an 500Gb DB

gbak version LI-V4.0.2.2816 Firebird 4.0

CentOS Linux release 7.9.2009 (Core)

gbak parameter:

/opt/firebird/bin/gbak -b -g -nod -t -st tdrw -skip_d '(tons)|(of)|(skipped)|(tables)' -v -y gbak db.fdb db.fbk

And reading the gbak output, I got this strange reads/writes values (truncated logs anexed) :

>gbak: time     delta  reads  writes

>...

>gbak:   16.581  0.000      0      9     writing data for table SERASA_PEFIN
>gbak:   16.588  0.006 18446744073708961517 18446744073703337429 1761 records written
>gbak:   16.588  0.000 590099 6214230     writing index RDB$PRIMARY204
>gbak:   16.588  0.000      0      7     writing data for table TMP$RELACAO_PRODUTO_COD_NF_FORN

Note that SERASA_PEFIN has only 1761 records with 4 int column values and a timestamp column, and the same occur in other tables, but as gbak hasn't finished yet I just send the first 2 tables anexed

Looks like some kind of overflow, not really a blocking bug, but reporting anyway
