- During prepare of incremental backup, mariabackup does create new file in target directory with default file size of 4 * innodb_page_size. While applying .delta file to corresponding data file, it encounters the FSP_SIZE modification on page0 and tries to extend the file to the size which is 4 in our case. Since the table is in compressed row format, page_size for the table is 8k. This lead to shrinking of tablespace file from 65536 to 32768. This issue happens only in windows because os_file_set_size() doesn't check for the current size and shrinks the file. Solution: ======== xtrabackup_apply_delta(): Check for the current size before doing setting size for the file.
