With a very volatile /tmp included, each snapshot will be much bigger, and the purging of old snapshots more painful.
Please see https://www.suse.com/documentation/sles-12/book_sle_admin/data/sec_snapper_s... PLEASE NOTE: This is discussing the *DEFAULT* setup. I've added emphasis that addresses the point your raised, John. <quote> As a result, partitions containing snapshots need to be larger than "normal" partitions. The exact amount strongly depends on the number of snapshots you keep and the amount of data modifications. As a rule of thumb you should consider using twice the size than you normally would. </quote> and more specifically <quote> Some directories need to be excluded from snapshots for different reasons. The following list shows all directories that are excluded: Directories that are Excluded from Snapshots /boot/grub2/i386-pc ,/boot/grub2/x86_64-efi, A rollback of the boot loader configuration is not supported. The directories listed above are architecture-specific. The first two directories are present on x86_64 machines, the latter two on IBM POWER and on IBM System z, respectively. /home If /home does not reside on a separate partition, it is excluded to avoid data loss on rollbacks. /opt, /var/opt Third-party products and add-ons usually get installed to /opt. It is excluded to avoid uninstalling these applications on rollbacks. /srv Contains data for Web and FTP servers. It is excluded to avoid data loss on rollbacks. */tmp*, */var/tmp*, /var/crash *All* *directories* *containing* *temporary* *files* *are* *excluded* *from* *snapshots*. /usr/local This directory is used when manually installing software. It is excluded to avoid uninstalling these installations on rollbacks. /var/lib/named Contains zone data for the DNS server. Excluded from snapshots to ensure a name server can operate after a rollback. /var/lib/mailman, /var/spool Directories containing mails or mail queues are excluded to avoid a loss of mails after a rollback. /var/lib/pgqsl Contains PostgreSQL data. /var/log Log file location. Excluded from snapshots to allow log file analysis after the rollback of a broken system. </quote> -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
