Backed up using
innobackupex /mnt/win/dbbackups/dms/ --encrypt = AES256 --encrypt-key=… – where '/mnt/win/dbbackups/dms/ is a smb mount

on recovery all but 1 file worked file but on the one file
getting

#xbcrypt -d --encrypt-algo=AES256 --encrypt-key=…< 217.ibd.qp.xbcrypt > 217.ibd.qp
xbcrypt:parse_xbcrypt_chunk: wrong chunk magic at offset 0x45bbbd5f0.
xbcrypt failed to decrypt: can’t write to output.
decrypt: failed to close dest file.

or with the -i / -o option…

xbcrypt -d --encrypt-algo=AES256 --encrypt-key=1726963861B24D16E28969C20BC3AE0A -i 217.ibd.qp.xbcrypt -o 217.ibd.qp

xbcrypt:parse_xbcrypt_chunk: wrong chunk magic at offset 0x45bbbd5f0.
xbcrypt failed to decrypt: can’t write to output.

is that file just corrupt?? any repair tools or way of recoving that?

Thanks
