Subject gbak /tmp minimum disk space
Author officialz
Recently I have noticed gbak failing to complete a backup/restore when
the disk space in my temporary folder is low and the database size is
large. I would like to add some automatic disk space checking before I
start up the backup/restore process. But, of course, I need to know
the minimum safe amount of disk space required for a backup/restore
for a database of a certain size.
Are there any specific guidelines I should be following?
I can probably assume a safe minimum is free_space>=database_size but
since the database could be fairly large, it would be nice to know if
gbak would not use more than a specific amount of free space, or a
specific percent of the database size, or maybe the size of the
largest table.
