ESXi 6.5 and rsync: "check files manually by using OpenSSL command"

Hello,

I want to use the rsync function of xsibackup to migrate my VMs from one server to another.
While running the xsibackup script, I get the following message:

"NOTICE: you are using ESXi 6.5.0, it contains some bugs that make it highly recommendable to use
XSIBACKUP-PRO's option --certify-backup. You can also check files manually by using OpenSSL command"

Does anybody know HOW to check the files with OpenSSL?

Best Regards,
CorSch

Re: ESXi 6.5 and rsync: "check files manually by using OpenSSL command"

a - openssl sha1 yourfile
b - openssl md5 yourfile
c - openssl md4 yourfile

Of course you have to run any of those commands on both sides and compare the obtained checksums. You may need to switch off your VM to perform the backup and the manual checksum comparison, as a running VM could change the contents of the open disks.

Not at all, just use openssl --help to get a list of all openssl digests:
