* Clarify that the -r and -R options can be used only to create level 0 dumps.Kirk McKusick2019-06-141-1/+13

* Revert size limits.Warner Losh2018-06-111-5/+0
| | | | | | | | | The size limits came from a flawed understanding of dump records. The real issue was that dump was bogusly interpreting c_count sometimes. r334978 fixes that. Notes: svn path=/head/; revision=334980

* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* When using dump to generate level 0 dumps which are then rsync'edKirk McKusick2008-05-231-1/+22
| | | | | | | | | | | | | | | to a remote machine, the fact that the dump date is stored with each header (inode) record makes rsync significantly less efficient than necessary. This also applies to inode access times when they are not important data to retain. When implementing an offsite backup solution of this type, these dates in particular are not important, especially if it prevents effective offsite backups.

* Add a caching option to dump. Use -C. Note that NetBSD has a caching optionMatthew Dillon2003-01-131-0/+11
| | | | | | | | | | | | | | | | | | | | | | called -r but it takes 512 byte blocks instead of megabytes, and I felt a megabytes specification would be far more useful so I did not use the same option character. This will *greatly* improve dump performance at the cost of possibly missing filesystem changes that occur between passes, and does a fairly good job making up for the loss of buffered block devices. Caching is disabled by default to retain historical behavior. In tests, dump performance improved by about 40% when dumping / or /usr. Beware that dump forks and the cache may wind up being larger then you specify, but a more complex shared memory implementation would not produce results that are all that much better so I kept it simple for now.

| | | | | | | | | | | | | | | | | | live filesystem. To obtain a consistent dump image, dump takes a snapshot of the filesystem and then does a dump of the snapshot. The snapshot is removed when the dump is complete. Also add an operator warning that the `L' option should be used if dump is run on a live filesystem without the `L' option being specified. The alternative would be to silently use a snapshot any time that a live filesystem is dumped, but this change in dump semantics seemed too drastic at this time. Sponsored by: DARPA & NAI Labs.
